79847258 divided by 620 
The aim is to understand the frequency of 620 in 79847258.

Let's proceed to step 1:
The number 620 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 620

Moving on to step 2:
When dividing 79 by 620, we get 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 620

Advancing to step 3:
If we divide 798 by 620, we get 1 and a remainder of 178.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 178 after subtracting 620 from 798.
Grab the next digit (4) from the dividend, add it to 178, then carry on: 1784 / 620

Let's proceed to step 4:
When dividing 1784 by 620, we get 2 with a remainder of 544.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1240 from 1784 leaves us with 544.
Fetch the next digit (7) from the dividend, attach it to 544 and continue: 5447 / 620

On to step 5:
620 goes into 5447 8 times with a remainder of 487.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Deduct 4960 from 5447 and we're left with 487.
Bring next digit (2) of the dividend behind the 487 and repeat the process: 4872 / 620

Step 6:
When dividing 4872 by 620, we get 7 with a remainder of 532.
Put 7 as the next digit of the answer. 
Result so far: 1287.0
Subtracting 4340 from 4872 leaves us with 532.
Fetch the next digit (5) from the dividend, attach it to 532 and continue: 5325 / 620

Let's proceed to step 7:
The number 620 fits into 5325 8 times, leaving a remainder of 365.
Use 8 as the next digit of our solution. 
Result so far: 12878.0
If we subtract 4960 from 5325, we get 365.
Fetch the next digit (8) from the dividend, attach it to 365 and continue: 3658 / 620

Step 8:
620 can be fit into 3658 5 times, resulting in a remainder of 558.
Put 5 as the next digit of the answer. 
Result so far: 128785.0
Subtracting 3100 from 3658 leaves us with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 9:
When dividing 5580 by 620, we get 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 128785.9
If we take 5580 away from 5580, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 620, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 128785.9
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
If we divide 0 by 620, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 128785.9
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 128785.9 with a remainder of 0.0.
