We look at the division of 90751 by 71 
The aim is to understand the frequency of 71 in 90751.

Advancing to step 1:
71 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 71

On to step 2:
71 goes into 90 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 71 from 90, we get 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 71

Advancing to step 3:
When dividing 197 by 71, we get 2 with a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 142 from 197 leaves us with 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 71

Step 4:
If we divide 555 by 71, we get 7 and a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
If we take 497 away from 555, we end up with 58.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 71

Let's proceed to step 5:
71 goes into 581 8 times with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 1278.0
If we take 568 away from 581, we end up 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.

Moving on to step 6:
130 divided by 71 is 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 1278.1
If we take 71 away from 130, we end up with 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 7:
590 divided by 71 is 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 1278.18
Subtracting 568 from 590 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
71 goes into 220 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 1278.183
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.

Let's proceed to step 9:
If we divide 70 by 71, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 1278.183
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.

Let's proceed to step 10:
71 can be fit into 700 9 times, resulting in a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 1278.18309
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.

Let's proceed to step 11:
The number 71 fits into 610 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 1278.183098
Subtracting 568 from 610 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
71 goes into 420 5 times with a remainder of 65.
The next digit of our result is 5. 
Result so far: 1278.1830985
If we subtract 355 from 420, we 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.

On to step 13:
650 divided by 71 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 1278.18309859
Deduct 639 from 650 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 1278.18309859, and the remainder is 1.1e-08.
