We look at the division of 15831064 by 758 
The aim is to understand the frequency of 758 in 15831064.

Advancing to step 1:
1 divided by 758 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 758

Step 2:
The number 758 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 758

Going ahead to step 3:
158 divided by 758 is 0 with a remainder of 158.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 158 and we're left with 158.
Bring next digit (3) of the dividend behind the 158 and repeat the process: 1583 / 758

Advancing to step 4:
758 can be fit into 1583 2 times, resulting in a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1516 away from 1583, we end up with 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 758

Going ahead to step 5:
758 can be fit into 671 0 times, resulting in a remainder of 671.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 671 to get 671.
Grab the next digit (0) from the dividend, add it to 671, then carry on: 6710 / 758

Advancing to step 6:
6710 divided by 758 is 8 with a remainder of 646.
Put 8 as the next digit of the answer. 
Result so far: 208.0
The remainder is 646 after subtracting 6064 from 6710.
Append the next digit (6) from the dividend to 646 and continue with: 6466 / 758

Advancing to step 7:
If we divide 6466 by 758, we get 8 and a remainder of 402.
Use 8 as the next digit of our solution. 
Result so far: 2088.0
If we take 6064 away from 6466, we end up with 402.
Grab the next digit (4) from the dividend, add it to 402, then carry on: 4024 / 758

On to step 8:
758 goes into 4024 5 times with a remainder of 234.
Write down 5 as next digit of the result. 
Result so far: 20885.0
The remainder is 234 after subtracting 3790 from 4024.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 9:
When dividing 2340 by 758, we get 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 20885.3
Deduct 2274 from 2340 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
758 goes into 660 0 times with a remainder of 660.
The number 0 becomes the next digit in our result. 
Result so far: 20885.3
Subtract 0 from 660 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 11:
The number 758 fits into 6600 8 times, leaving a remainder of 536.
The next digit of our result is 8. 
Result so far: 20885.308
Subtracting 6064 from 6600 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

On to step 12:
If we divide 5360 by 758, we get 7 and a remainder of 54.
The next digit of our result is 7. 
Result so far: 20885.3087
If we subtract 5306 from 5360, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 13:
When dividing 540 by 758, we get 0 with a remainder of 540.
Record the quotient 0 as the next digit in the result. 
Result so far: 20885.3087
Subtracting 0 from 540 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 14:
5400 divided by 758 is 7 with a remainder of 94.
Write down 7 as next digit of the result. 
Result so far: 20885.308707
If we subtract 5306 from 5400, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 15:
If we divide 940 by 758, we get 1 and a remainder of 182.
Record the quotient 1 as the next digit in the result. 
Result so far: 20885.3087071
Subtract 758 from 940 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 16:
758 goes into 1820 2 times with a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 20885.30870712
Subtract 1516 from 1820 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final outcome is 20885.30870712, with a leftover of 3.04e-07.
