We divide 81122301 by 871
The aim is to understand the frequency of 871 in 81122301.

Going ahead to step 1:
The number 871 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 871

Going ahead to step 2:
The number 871 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 871

On to step 3:
871 goes into 811 0 times with a remainder of 811.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 811, we end up with 811.
Include the next digit (2) from the dividend after 811, then repeat: 8112 / 871

Moving on to step 4:
When dividing 8112 by 871, we get 9 with a remainder of 273.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7839 from 8112, we get 273.
Grab the next digit (2) from the dividend, add it to 273, then carry on: 2732 / 871

Going ahead to step 5:
2732 divided by 871 is 3 with a remainder of 119.
Put 3 as the next digit of the answer. 
Result so far: 93.0
Deduct 2613 from 2732 and we're left with 119.
Include the next digit (3) from the dividend after 119, then repeat: 1193 / 871

Step 6:
1193 divided by 871 is 1 with a remainder of 322.
Use 1 as the next digit of our solution. 
Result so far: 931.0
Subtract 871 from 1193 to get 322.
Grab the next digit (0) from the dividend, add it to 322, then carry on: 3220 / 871

Step 7:
871 goes into 3220 3 times with a remainder of 607.
Record the quotient 3 as the next digit in the result. 
Result so far: 9313.0
The remainder is 607 after subtracting 2613 from 3220.
Include the next digit (1) from the dividend after 607, then repeat: 6071 / 871

Going ahead to step 8:
871 goes into 6071 6 times with a remainder of 845.
Use 6 as the next digit of our solution. 
Result so far: 93136.0
Deduct 5226 from 6071 and we're left with 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

Moving on to step 9:
If we divide 8450 by 871, we get 9 and a remainder of 611.
Record the quotient 9 as the next digit in the result. 
Result so far: 93136.9
Deduct 7839 from 8450 and we're left with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Let's proceed to step 10:
The number 871 fits into 6110 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 93136.97
If we subtract 6097 from 6110, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
871 goes into 130 0 times with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 93136.97
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 12:
871 can be fit into 1300 1 times, resulting in a remainder of 429.
The next digit of our result is 1. 
Result so far: 93136.9701
Deduct 871 from 1300 and we're left with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Moving on to step 13:
If we divide 4290 by 871, we get 4 and a remainder of 806.
Use 4 as the next digit of our solution. 
Result so far: 93136.97014
Subtracting 3484 from 4290 leaves us with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Advancing to step 14:
871 goes into 8060 9 times with a remainder of 221.
The number 9 becomes the next digit in our result. 
Result so far: 93136.970149
The remainder is 221 after subtracting 7839 from 8060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 15:
When dividing 2210 by 871, we get 2 with a remainder of 468.
The number 2 becomes the next digit in our result. 
Result so far: 93136.9701492
If we take 1742 away from 2210, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 16:
4680 divided by 871 is 5 with a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 93136.97014925
If we take 4355 away from 4680, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Our division results in 93136.97014925 with a remaining 3.25e-07.
