We divide 74901022 by 831
The aim is to understand the frequency of 831 in 74901022.

Step 1:
If we divide 7 by 831, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 831

Going ahead to step 2:
831 can be fit into 74 0 times, resulting in a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 831

Step 3:
When dividing 749 by 831, we get 0 with a remainder of 749.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 749, we end up with 749.
Fetch the next digit (0) from the dividend, attach it to 749 and continue: 7490 / 831

Step 4:
If we divide 7490 by 831, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 11 after subtracting 7479 from 7490.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 831

On to step 5:
When dividing 111 by 831, we get 0 with a remainder of 111.
The next digit of our result is 0. 
Result so far: 90.0
The remainder is 111 after subtracting 0 from 111.
Append the next digit (0) from the dividend to 111 and continue with: 1110 / 831

On to step 6:
If we divide 1110 by 831, we get 1 and a remainder of 279.
The next digit of our result is 1. 
Result so far: 901.0
Subtracting 831 from 1110 leaves us with 279.
Grab the next digit (2) from the dividend, add it to 279, then carry on: 2792 / 831

Advancing to step 7:
If we divide 2792 by 831, we get 3 and a remainder of 299.
Put 3 as the next digit of the answer. 
Result so far: 9013.0
If we subtract 2493 from 2792, we get 299.
Append the next digit (2) from the dividend to 299 and continue with: 2992 / 831

Moving on to step 8:
2992 divided by 831 is 3 with a remainder of 499.
The next digit of our result is 3. 
Result so far: 90133.0
Subtract 2493 from 2992 to get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Moving on to step 9:
If we divide 4990 by 831, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 90133.6
If we take 4986 away from 4990, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
The number 831 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 90133.6
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
If we divide 400 by 831, we get 0 and a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 90133.6
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 90133.6, with a leftover of 0.04.
