We're dividing 14856980 by 831 
The aim is to understand the frequency of 831 in 14856980.

On to step 1:
1 divided by 831 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 831

Advancing to step 2:
If we divide 14 by 831, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 831

Advancing to step 3:
The number 831 fits into 148 0 times, leaving a remainder of 148.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 148 after subtracting 0 from 148.
Include the next digit (5) from the dividend after 148, then repeat: 1485 / 831

Advancing to step 4:
831 can be fit into 1485 1 times, resulting in a remainder of 654.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 831 from 1485 leaves us with 654.
Fetch the next digit (6) from the dividend, attach it to 654 and continue: 6546 / 831

On to step 5:
831 can be fit into 6546 7 times, resulting in a remainder of 729.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 5817 from 6546 and we're left with 729.
Bring next digit (9) of the dividend behind the 729 and repeat the process: 7299 / 831

Advancing to step 6:
When dividing 7299 by 831, we get 8 with a remainder of 651.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
If we take 6648 away from 7299, we end up with 651.
Append the next digit (8) from the dividend to 651 and continue with: 6518 / 831

Moving on to step 7:
831 can be fit into 6518 7 times, resulting in a remainder of 701.
Write down 7 as next digit of the result. 
Result so far: 1787.0
Deduct 5817 from 6518 and we're left with 701.
Include the next digit (0) from the dividend after 701, then repeat: 7010 / 831

Advancing to step 8:
831 goes into 7010 8 times with a remainder of 362.
Write down 8 as next digit of the result. 
Result so far: 17878.0
If we subtract 6648 from 7010, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 9:
831 can be fit into 3620 4 times, resulting in a remainder of 296.
Use 4 as the next digit of our solution. 
Result so far: 17878.4
Subtracting 3324 from 3620 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 10:
When dividing 2960 by 831, we get 3 with a remainder of 467.
Use 3 as the next digit of our solution. 
Result so far: 17878.43
If we subtract 2493 from 2960, we get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

On to step 11:
831 goes into 4670 5 times with a remainder of 515.
The next digit of our result is 5. 
Result so far: 17878.435
Deduct 4155 from 4670 and we're left with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 12:
When dividing 5150 by 831, we get 6 with a remainder of 164.
Record the quotient 6 as the next digit in the result. 
Result so far: 17878.4356
If we subtract 4986 from 5150, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 13:
If we divide 1640 by 831, we get 1 and a remainder of 809.
Write down 1 as next digit of the result. 
Result so far: 17878.43561
If we take 831 away from 1640, we end up with 809.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8090, and continue the process.

Moving on to step 14:
If we divide 8090 by 831, we get 9 and a remainder of 611.
Write down 9 as next digit of the result. 
Result so far: 17878.435619
Subtracting 7479 from 8090 leaves us with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Step 15:
The number 831 fits into 6110 7 times, leaving a remainder of 293.
The next digit of our result is 7. 
Result so far: 17878.4356197
Subtract 5817 from 6110 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 16:
If we divide 2930 by 831, we get 3 and a remainder of 437.
Record the quotient 3 as the next digit in the result. 
Result so far: 17878.43561973
Deduct 2493 from 2930 and we're left with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

In conclusion, the division gives 17878.43561973 with a balance of 4.37e-07.
