86982904 ÷ 931 
The aim is to understand the frequency of 931 in 86982904.

On to step 1:
When dividing 8 by 931, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 931

Advancing to step 2:
If we divide 86 by 931, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 931

Let's proceed to step 3:
869 divided by 931 is 0 with a remainder of 869.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 869 to get 869.
Bring next digit (8) of the dividend behind the 869 and repeat the process: 8698 / 931

On to step 4:
When dividing 8698 by 931, we get 9 with a remainder of 319.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 8379 from 8698 and we're left with 319.
Take the next digit (2) from the dividend and append it to 319, then repeat: 3192 / 931

Going ahead to step 5:
3192 divided by 931 is 3 with a remainder of 399.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we take 2793 away from 3192, we end up with 399.
Grab the next digit (9) from the dividend, add it to 399, then carry on: 3999 / 931

Advancing to step 6:
When dividing 3999 by 931, we get 4 with a remainder of 275.
Use 4 as the next digit of our solution. 
Result so far: 934.0
Deduct 3724 from 3999 and we're left with 275.
Fetch the next digit (0) from the dividend, attach it to 275 and continue: 2750 / 931

Moving on to step 7:
When dividing 2750 by 931, we get 2 with a remainder of 888.
Use 2 as the next digit of our solution. 
Result so far: 9342.0
Deduct 1862 from 2750 and we're left with 888.
Grab the next digit (4) from the dividend, add it to 888, then carry on: 8884 / 931

Going ahead to step 8:
8884 divided by 931 is 9 with a remainder of 505.
Record the quotient 9 as the next digit in the result. 
Result so far: 93429.0
Subtracting 8379 from 8884 leaves us with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 9:
5050 divided by 931 is 5 with a remainder of 395.
Record the quotient 5 as the next digit in the result. 
Result so far: 93429.5
Deduct 4655 from 5050 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 10:
931 can be fit into 3950 4 times, resulting in a remainder of 226.
The number 4 becomes the next digit in our result. 
Result so far: 93429.54
If we take 3724 away from 3950, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 11:
If we divide 2260 by 931, we get 2 and a remainder of 398.
Record the quotient 2 as the next digit in the result. 
Result so far: 93429.542
Subtract 1862 from 2260 to get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 12:
931 can be fit into 3980 4 times, resulting in a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 93429.5424
The remainder is 256 after subtracting 3724 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 13:
When dividing 2560 by 931, we get 2 with a remainder of 698.
Write down 2 as next digit of the result. 
Result so far: 93429.54242
Subtract 1862 from 2560 to get 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Step 14:
When dividing 6980 by 931, we get 7 with a remainder of 463.
Use 7 as the next digit of our solution. 
Result so far: 93429.542427
If we subtract 6517 from 6980, we get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Going ahead to step 15:
When dividing 4630 by 931, we get 4 with a remainder of 906.
Write down 4 as next digit of the result. 
Result so far: 93429.5424274
Deduct 3724 from 4630 and we're left with 906.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9060, and continue the process.

Moving on to step 16:
931 goes into 9060 9 times with a remainder of 681.
The next digit of our result is 9. 
Result so far: 93429.54242749
The remainder is 681 after subtracting 8379 from 9060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

The quotient of the division is 93429.54242749, and the remainder is 6.81e-07.
