Let's divide 42560991 by 931
The aim is to understand the frequency of 931 in 42560991.

Going ahead to step 1:
931 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 931

Advancing to step 2:
42 divided by 931 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 931

Step 3:
931 can be fit into 425 0 times, resulting in a remainder of 425.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 425, we get 425.
Grab the next digit (6) from the dividend, add it to 425, then carry on: 4256 / 931

Let's proceed to step 4:
If we divide 4256 by 931, we get 4 and a remainder of 532.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 3724 away from 4256, we end up with 532.
Take the next digit (0) from the dividend and append it to 532, then repeat: 5320 / 931

Going ahead to step 5:
931 goes into 5320 5 times with a remainder of 665.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we take 4655 away from 5320, we end up with 665.
Append the next digit (9) from the dividend to 665 and continue with: 6659 / 931

Let's proceed to step 6:
The number 931 fits into 6659 7 times, leaving a remainder of 142.
Write down 7 as next digit of the result. 
Result so far: 457.0
If we take 6517 away from 6659, we end up with 142.
Bring next digit (9) of the dividend behind the 142 and repeat the process: 1429 / 931

Moving on to step 7:
1429 divided by 931 is 1 with a remainder of 498.
Write down 1 as next digit of the result. 
Result so far: 4571.0
Subtract 931 from 1429 to get 498.
Bring next digit (1) of the dividend behind the 498 and repeat the process: 4981 / 931

On to step 8:
931 goes into 4981 5 times with a remainder of 326.
The number 5 becomes the next digit in our result. 
Result so far: 45715.0
The remainder is 326 after subtracting 4655 from 4981.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 9:
When dividing 3260 by 931, we get 3 with a remainder of 467.
Write down 3 as next digit of the result. 
Result so far: 45715.3
If we take 2793 away from 3260, we end up with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Going ahead to step 10:
931 goes into 4670 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 45715.35
Deduct 4655 from 4670 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
The number 931 fits into 150 0 times, leaving a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 45715.35
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
1500 divided by 931 is 1 with a remainder of 569.
The number 1 becomes the next digit in our result. 
Result so far: 45715.3501
If we subtract 931 from 1500, we get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Advancing to step 13:
If we divide 5690 by 931, we get 6 and a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 45715.35016
Subtract 5586 from 5690 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 14:
931 goes into 1040 1 times with a remainder of 109.
The next digit of our result is 1. 
Result so far: 45715.350161
If we subtract 931 from 1040, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 15:
When dividing 1090 by 931, we get 1 with a remainder of 159.
Write down 1 as next digit of the result. 
Result so far: 45715.3501611
Deduct 931 from 1090 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

The final result is 45715.3501611 with a remainder of 1.59e-06.
