We look at the division of 93783020 by 620 
The aim is to understand the frequency of 620 in 93783020.

Advancing to step 1:
If we divide 9 by 620, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 620

Step 2:
93 divided by 620 is 0 with a remainder of 93.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 93 after subtracting 0 from 93.
Take the next digit (7) from the dividend and append it to 93, then repeat: 937 / 620

On to step 3:
The number 620 fits into 937 1 times, leaving a remainder of 317.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 620 from 937 and we're left with 317.
Grab the next digit (8) from the dividend, add it to 317, then carry on: 3178 / 620

Moving on to step 4:
620 can be fit into 3178 5 times, resulting in a remainder of 78.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 3100 away from 3178, we end up with 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 620

Advancing to step 5:
If we divide 783 by 620, we get 1 and a remainder of 163.
Write down 1 as next digit of the result. 
Result so far: 151.0
Subtracting 620 from 783 leaves us with 163.
Include the next digit (0) from the dividend after 163, then repeat: 1630 / 620

Going ahead to step 6:
620 goes into 1630 2 times with a remainder of 390.
Write down 2 as next digit of the result. 
Result so far: 1512.0
If we subtract 1240 from 1630, we get 390.
Fetch the next digit (2) from the dividend, attach it to 390 and continue: 3902 / 620

On to step 7:
3902 divided by 620 is 6 with a remainder of 182.
Record the quotient 6 as the next digit in the result. 
Result so far: 15126.0
If we subtract 3720 from 3902, we get 182.
Fetch the next digit (0) from the dividend, attach it to 182 and continue: 1820 / 620

Moving on to step 8:
When dividing 1820 by 620, we get 2 with a remainder of 580.
Use 2 as the next digit of our solution. 
Result so far: 151262.0
If we subtract 1240 from 1820, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 9:
5800 divided by 620 is 9 with a remainder of 220.
Record the quotient 9 as the next digit in the result. 
Result so far: 151262.9
If we take 5580 away from 5800, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
620 goes into 2200 3 times with a remainder of 340.
Put 3 as the next digit of the answer. 
Result so far: 151262.93
If we subtract 1860 from 2200, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 11:
3400 divided by 620 is 5 with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 151262.935
Deduct 3100 from 3400 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 12:
620 can be fit into 3000 4 times, resulting in a remainder of 520.
The number 4 becomes the next digit in our result. 
Result so far: 151262.9354
The remainder is 520 after subtracting 2480 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 13:
620 can be fit into 5200 8 times, resulting in a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 151262.93548
The remainder is 240 after subtracting 4960 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 14:
620 can be fit into 2400 3 times, resulting in a remainder of 540.
Use 3 as the next digit of our solution. 
Result so far: 151262.935483
Deduct 1860 from 2400 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 15:
If we divide 5400 by 620, we get 8 and a remainder of 440.
Record the quotient 8 as the next digit in the result. 
Result so far: 151262.9354838
Deduct 4960 from 5400 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 16:
The number 620 fits into 4400 7 times, leaving a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 151262.93548387
Deduct 4340 from 4400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 151262.93548387 and a remainder of 6e-08.
