37135446 divided by 871 
The aim is to understand the frequency of 871 in 37135446.

Let's proceed to step 1:
3 divided by 871 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 871

On to step 2:
871 can be fit into 37 0 times, resulting in a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 871

On to step 3:
The number 871 fits into 371 0 times, leaving a remainder of 371.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 371 after subtracting 0 from 371.
Append the next digit (3) from the dividend to 371 and continue with: 3713 / 871

Going ahead to step 4:
The number 871 fits into 3713 4 times, leaving a remainder of 229.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3484 from 3713 and we're left with 229.
Append the next digit (5) from the dividend to 229 and continue with: 2295 / 871

On to step 5:
2295 divided by 871 is 2 with a remainder of 553.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we take 1742 away from 2295, we end up with 553.
Grab the next digit (4) from the dividend, add it to 553, then carry on: 5534 / 871

On to step 6:
871 can be fit into 5534 6 times, resulting in a remainder of 308.
Record the quotient 6 as the next digit in the result. 
Result so far: 426.0
The remainder is 308 after subtracting 5226 from 5534.
Fetch the next digit (4) from the dividend, attach it to 308 and continue: 3084 / 871

Moving on to step 7:
The number 871 fits into 3084 3 times, leaving a remainder of 471.
Use 3 as the next digit of our solution. 
Result so far: 4263.0
If we take 2613 away from 3084, we end up with 471.
Grab the next digit (6) from the dividend, add it to 471, then carry on: 4716 / 871

Advancing to step 8:
871 goes into 4716 5 times with a remainder of 361.
The next digit of our result is 5. 
Result so far: 42635.0
The remainder is 361 after subtracting 4355 from 4716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 9:
The number 871 fits into 3610 4 times, leaving a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 42635.4
The remainder is 126 after subtracting 3484 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 10:
871 can be fit into 1260 1 times, resulting in a remainder of 389.
Use 1 as the next digit of our solution. 
Result so far: 42635.41
If we take 871 away from 1260, we end up with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Step 11:
871 goes into 3890 4 times with a remainder of 406.
Record the quotient 4 as the next digit in the result. 
Result so far: 42635.414
If we take 3484 away from 3890, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 12:
The number 871 fits into 4060 4 times, leaving a remainder of 576.
The number 4 becomes the next digit in our result. 
Result so far: 42635.4144
Deduct 3484 from 4060 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The final result is 42635.4144 with a remainder of 0.00576.
