Let's divide 3989120 by 936
The aim is to understand the frequency of 936 in 3989120.

Moving on to step 1:
936 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 936

Going ahead to step 2:
The number 936 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 936

Moving on to step 3:
The number 936 fits into 398 0 times, leaving a remainder of 398.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 398 after subtracting 0 from 398.
Take the next digit (9) from the dividend and append it to 398, then repeat: 3989 / 936

Advancing to step 4:
The number 936 fits into 3989 4 times, leaving a remainder of 245.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3744 from 3989 and we're left with 245.
Include the next digit (1) from the dividend after 245, then repeat: 2451 / 936

Going ahead to step 5:
When dividing 2451 by 936, we get 2 with a remainder of 579.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we subtract 1872 from 2451, we get 579.
Grab the next digit (2) from the dividend, add it to 579, then carry on: 5792 / 936

On to step 6:
When dividing 5792 by 936, we get 6 with a remainder of 176.
Record the quotient 6 as the next digit in the result. 
Result so far: 426.0
Deduct 5616 from 5792 and we're left with 176.
Append the next digit (0) from the dividend to 176 and continue with: 1760 / 936

Going ahead to step 7:
If we divide 1760 by 936, we get 1 and a remainder of 824.
The next digit of our result is 1. 
Result so far: 4261.0
If we subtract 936 from 1760, we get 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Going ahead to step 8:
8240 divided by 936 is 8 with a remainder of 752.
The number 8 becomes the next digit in our result. 
Result so far: 4261.8
Deduct 7488 from 8240 and we're left with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Advancing to step 9:
7520 divided by 936 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 4261.88
Subtract 7488 from 7520 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 4261.88 and a remainder of 0.032.
