We divide 38571535 by 639
The aim is to understand the frequency of 639 in 38571535.

Moving on to step 1:
639 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 639

Step 2:
639 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 639

Moving on to step 3:
639 can be fit into 385 0 times, resulting in a remainder of 385.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 385 and we're left with 385.
Grab the next digit (7) from the dividend, add it to 385, then carry on: 3857 / 639

Going ahead to step 4:
3857 divided by 639 is 6 with a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 3834 from 3857 and we're left with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 639

On to step 5:
The number 639 fits into 231 0 times, leaving a remainder of 231.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
The remainder is 231 after subtracting 0 from 231.
Fetch the next digit (5) from the dividend, attach it to 231 and continue: 2315 / 639

Going ahead to step 6:
2315 divided by 639 is 3 with a remainder of 398.
Write down 3 as next digit of the result. 
Result so far: 603.0
If we subtract 1917 from 2315, we get 398.
Bring next digit (3) of the dividend behind the 398 and repeat the process: 3983 / 639

Going ahead to step 7:
639 can be fit into 3983 6 times, resulting in a remainder of 149.
Record the quotient 6 as the next digit in the result. 
Result so far: 6036.0
If we take 3834 away from 3983, we end up with 149.
Append the next digit (5) from the dividend to 149 and continue with: 1495 / 639

Moving on to step 8:
639 can be fit into 1495 2 times, resulting in a remainder of 217.
Record the quotient 2 as the next digit in the result. 
Result so far: 60362.0
The remainder is 217 after subtracting 1278 from 1495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 9:
When dividing 2170 by 639, we get 3 with a remainder of 253.
Record the quotient 3 as the next digit in the result. 
Result so far: 60362.3
Subtract 1917 from 2170 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 10:
639 goes into 2530 3 times with a remainder of 613.
The number 3 becomes the next digit in our result. 
Result so far: 60362.33
Subtract 1917 from 2530 to get 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

After the division, we end up with 60362.33 and a remainder of 0.613.
