36707375 divided by 871 
The aim is to understand the frequency of 871 in 36707375.

On to step 1:
If we divide 3 by 871, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 871

Moving on to step 2:
If we divide 36 by 871, we get 0 and a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Grab the next digit (7) from the dividend, add it to 36, then carry on: 367 / 871

Going ahead to step 3:
If we divide 367 by 871, we get 0 and a remainder of 367.
The next digit of our result is 0. 
Result so far: 0.0

Grab the next digit (0) from the dividend, add it to 367, then carry on: 3670 / 871

Moving on to step 4:
If we divide 3670 by 871, we get 4 and a remainder of 186.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3484 from 3670 and we're left with 186.
Fetch the next digit (7) from the dividend, attach it to 186 and continue: 1867 / 871

Step 5:
If we divide 1867 by 871, we get 2 and a remainder of 125.
The next digit of our result is 2. 
Result so far: 42.0
If we take 1742 away from 1867, we end up with 125.
Take the next digit (3) from the dividend and append it to 125, then repeat: 1253 / 871

Going ahead to step 6:
If we divide 1253 by 871, we get 1 and a remainder of 382.
Put 1 as the next digit of the answer. 
Result so far: 421.0
Deduct 871 from 1253 and we're left with 382.
Bring next digit (7) of the dividend behind the 382 and repeat the process: 3827 / 871

Going ahead to step 7:
When dividing 3827 by 871, we get 4 with a remainder of 343.
Use 4 as the next digit of our solution. 
Result so far: 4214.0
If we subtract 3484 from 3827, we get 343.
Grab the next digit (5) from the dividend, add it to 343, then carry on: 3435 / 871

Moving on to step 8:
The number 871 fits into 3435 3 times, leaving a remainder of 822.
Write down 3 as next digit of the result. 
Result so far: 42143.0
The remainder is 822 after subtracting 2613 from 3435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

On to step 9:
When dividing 8220 by 871, we get 9 with a remainder of 381.
Write down 9 as next digit of the result. 
Result so far: 42143.9
If we subtract 7839 from 8220, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Moving on to step 10:
When dividing 3810 by 871, we get 4 with a remainder of 326.
Use 4 as the next digit of our solution. 
Result so far: 42143.94
If we take 3484 away from 3810, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 11:
When dividing 3260 by 871, we get 3 with a remainder of 647.
Use 3 as the next digit of our solution. 
Result so far: 42143.943
The remainder is 647 after subtracting 2613 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Step 12:
871 can be fit into 6470 7 times, resulting in a remainder of 373.
Put 7 as the next digit of the answer. 
Result so far: 42143.9437
If we take 6097 away from 6470, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 13:
871 can be fit into 3730 4 times, resulting in a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 42143.94374
If we take 3484 away from 3730, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 14:
When dividing 2460 by 871, we get 2 with a remainder of 718.
Record the quotient 2 as the next digit in the result. 
Result so far: 42143.943742
If we subtract 1742 from 2460, we get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Going ahead to step 15:
When dividing 7180 by 871, we get 8 with a remainder of 212.
Use 8 as the next digit of our solution. 
Result so far: 42143.9437428
Deduct 6968 from 7180 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 16:
871 goes into 2120 2 times with a remainder of 378.
The number 2 becomes the next digit in our result. 
Result so far: 42143.94374282
Subtract 1742 from 2120 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The final outcome is 42143.94374282, with a leftover of 3.78e-07.
