Let's divide 38085622 by 621
The aim is to understand the frequency of 621 in 38085622.

Moving on to step 1:
621 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 621

Moving on to step 2:
38 divided by 621 is 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 621

On to step 3:
380 divided by 621 is 0 with a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 380 to get 380.
Grab the next digit (8) from the dividend, add it to 380, then carry on: 3808 / 621

Going ahead to step 4:
621 goes into 3808 6 times with a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 3726 from 3808 and we're left with 82.
Take the next digit (5) from the dividend and append it to 82, then repeat: 825 / 621

Moving on to step 5:
825 divided by 621 is 1 with a remainder of 204.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
If we take 621 away from 825, we end up with 204.
Append the next digit (6) from the dividend to 204 and continue with: 2046 / 621

Moving on to step 6:
621 goes into 2046 3 times with a remainder of 183.
Put 3 as the next digit of the answer. 
Result so far: 613.0
Deduct 1863 from 2046 and we're left with 183.
Fetch the next digit (2) from the dividend, attach it to 183 and continue: 1832 / 621

Going ahead to step 7:
When dividing 1832 by 621, we get 2 with a remainder of 590.
Write down 2 as next digit of the result. 
Result so far: 6132.0
Deduct 1242 from 1832 and we're left with 590.
Take the next digit (2) from the dividend and append it to 590, then repeat: 5902 / 621

Moving on to step 8:
5902 divided by 621 is 9 with a remainder of 313.
The number 9 becomes the next digit in our result. 
Result so far: 61329.0
Subtract 5589 from 5902 to get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Moving on to step 9:
If we divide 3130 by 621, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 61329.5
Subtract 3105 from 3130 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
621 goes into 250 0 times with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 61329.5
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 11:
621 can be fit into 2500 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 61329.504
If we subtract 2484 from 2500, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
If we divide 160 by 621, we get 0 and a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 61329.504
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
If we divide 1600 by 621, we get 2 and a remainder of 358.
Record the quotient 2 as the next digit in the result. 
Result so far: 61329.50402
If we subtract 1242 from 1600, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 14:
The number 621 fits into 3580 5 times, leaving a remainder of 475.
Record the quotient 5 as the next digit in the result. 
Result so far: 61329.504025
If we take 3105 away from 3580, we end up with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Step 15:
If we divide 4750 by 621, we get 7 and a remainder of 403.
The number 7 becomes the next digit in our result. 
Result so far: 61329.5040257
Subtracting 4347 from 4750 leaves us with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Let's proceed to step 16:
The number 621 fits into 4030 6 times, leaving a remainder of 304.
Write down 6 as next digit of the result. 
Result so far: 61329.50402576
Subtracting 3726 from 4030 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

After the division, we end up with 61329.50402576 and a remainder of 3.04e-07.
