39401 ÷ 83 
The aim is to understand the frequency of 83 in 39401.

Step 1:
83 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 83

On to step 2:
83 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 83

Let's proceed to step 3:
83 goes into 394 4 times with a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 332 from 394 leaves us with 62.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 83

Let's proceed to step 4:
83 goes into 620 7 times with a remainder of 39.
The next digit of our result is 7. 
Result so far: 47.0
Deduct 581 from 620 and we're left with 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 83

Advancing to step 5:
391 divided by 83 is 4 with a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 474.0
Subtract 332 from 391 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 6:
If we divide 590 by 83, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 474.7
If we take 581 away from 590, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
When dividing 90 by 83, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 474.71
Deduct 83 from 90 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
If we divide 70 by 83, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 474.71
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
If we divide 700 by 83, we get 8 and a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 474.7108
Subtract 664 from 700 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
The number 83 fits into 360 4 times, leaving a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 474.71084
If we subtract 332 from 360, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
83 goes into 280 3 times with a remainder of 31.
The next digit of our result is 3. 
Result so far: 474.710843
The remainder is 31 after subtracting 249 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 12:
When dividing 310 by 83, we get 3 with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 474.7108433
The remainder is 61 after subtracting 249 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 474.7108433 and a remainder of 6.1e-07.
