73348602 ÷ 831 
The aim is to understand the frequency of 831 in 73348602.

On to step 1:
831 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 831

Step 2:
The number 831 fits into 73 0 times, leaving a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Append the next digit (3) from the dividend to 73 and continue with: 733 / 831

Going ahead to step 3:
831 can be fit into 733 0 times, resulting in a remainder of 733.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 733 after subtracting 0 from 733.
Grab the next digit (4) from the dividend, add it to 733, then carry on: 7334 / 831

Going ahead to step 4:
831 can be fit into 7334 8 times, resulting in a remainder of 686.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 6648 from 7334 and we're left with 686.
Bring next digit (8) of the dividend behind the 686 and repeat the process: 6868 / 831

Going ahead to step 5:
831 goes into 6868 8 times with a remainder of 220.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtract 6648 from 6868 to get 220.
Include the next digit (6) from the dividend after 220, then repeat: 2206 / 831

On to step 6:
If we divide 2206 by 831, we get 2 and a remainder of 544.
Write down 2 as next digit of the result. 
Result so far: 882.0
If we subtract 1662 from 2206, we get 544.
Grab the next digit (0) from the dividend, add it to 544, then carry on: 5440 / 831

Step 7:
831 can be fit into 5440 6 times, resulting in a remainder of 454.
The number 6 becomes the next digit in our result. 
Result so far: 8826.0
Deduct 4986 from 5440 and we're left with 454.
Append the next digit (2) from the dividend to 454 and continue with: 4542 / 831

Moving on to step 8:
When dividing 4542 by 831, we get 5 with a remainder of 387.
Use 5 as the next digit of our solution. 
Result so far: 88265.0
Subtract 4155 from 4542 to get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Moving on to step 9:
831 goes into 3870 4 times with a remainder of 546.
Record the quotient 4 as the next digit in the result. 
Result so far: 88265.4
The remainder is 546 after subtracting 3324 from 3870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Advancing to step 10:
If we divide 5460 by 831, we get 6 and a remainder of 474.
Use 6 as the next digit of our solution. 
Result so far: 88265.46
Deduct 4986 from 5460 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 11:
831 can be fit into 4740 5 times, resulting in a remainder of 585.
Write down 5 as next digit of the result. 
Result so far: 88265.465
Deduct 4155 from 4740 and we're left with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Going ahead to step 12:
If we divide 5850 by 831, we get 7 and a remainder of 33.
The next digit of our result is 7. 
Result so far: 88265.4657
Subtracting 5817 from 5850 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 13:
831 can be fit into 330 0 times, resulting in a remainder of 330.
Write down 0 as next digit of the result. 
Result so far: 88265.4657
The remainder is 330 after subtracting 0 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 14:
The number 831 fits into 3300 3 times, leaving a remainder of 807.
Use 3 as the next digit of our solution. 
Result so far: 88265.465703
Subtracting 2493 from 3300 leaves us with 807.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8070, and continue the process.

On to step 15:
If we divide 8070 by 831, we get 9 and a remainder of 591.
Write down 9 as next digit of the result. 
Result so far: 88265.4657039
The remainder is 591 after subtracting 7479 from 8070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

On to step 16:
The number 831 fits into 5910 7 times, leaving a remainder of 93.
Record the quotient 7 as the next digit in the result. 
Result so far: 88265.46570397
If we take 5817 away from 5910, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

After the division, we end up with 88265.46570397 and a remainder of 9.3e-08.
