Let's divide 84570456 by 71
The aim is to understand the frequency of 71 in 84570456.

Going ahead to step 1:
When dividing 8 by 71, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 71

Going ahead to step 2:
The number 71 fits into 84 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 71 from 84 leaves us with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 71

On to step 3:
71 can be fit into 135 1 times, resulting in a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 71 away from 135, we end up with 64.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 71

Advancing to step 4:
71 goes into 647 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 119.0
If we subtract 639 from 647, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 71

Step 5:
71 goes into 80 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1191.0
The remainder is 9 after subtracting 71 from 80.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 71

Step 6:
71 goes into 94 1 times with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 11911.0
If we subtract 71 from 94, we get 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 71

Moving on to step 7:
71 can be fit into 235 3 times, resulting in a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 119113.0
Deduct 213 from 235 and we're left with 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 71

Going ahead to step 8:
226 divided by 71 is 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 1191133.0
Subtracting 213 from 226 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
If we divide 130 by 71, we get 1 and a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 1191133.1
If we subtract 71 from 130, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 10:
71 goes into 590 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 1191133.18
If we subtract 568 from 590, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
When dividing 220 by 71, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 1191133.183
If we take 213 away from 220, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
71 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 1191133.183
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
When dividing 700 by 71, we get 9 with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 1191133.18309
Deduct 639 from 700 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 14:
71 can be fit into 610 8 times, resulting in a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 1191133.183098
Subtract 568 from 610 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 15:
If we divide 420 by 71, we get 5 and a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 1191133.1830985
Subtract 355 from 420 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 16:
71 can be fit into 650 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 1191133.18309859
If we subtract 639 from 650, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 1191133.18309859 and a remainder of 1.1e-08.
