We're dividing 87848835 by 171 
The aim is to understand the frequency of 171 in 87848835.

Step 1:
171 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 171

Advancing to step 2:
171 goes into 87 0 times with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Append the next digit (8) from the dividend to 87 and continue with: 878 / 171

Going ahead to step 3:
171 can be fit into 878 5 times, resulting in a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 855 from 878, we get 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 171

Advancing to step 4:
When dividing 234 by 171, we get 1 with a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 171 from 234 leaves us with 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 171

Advancing to step 5:
171 can be fit into 638 3 times, resulting in a remainder of 125.
The number 3 becomes the next digit in our result. 
Result so far: 513.0
The remainder is 125 after subtracting 513 from 638.
Take the next digit (8) from the dividend and append it to 125, then repeat: 1258 / 171

Going ahead to step 6:
1258 divided by 171 is 7 with a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 5137.0
Subtracting 1197 from 1258 leaves us with 61.
Include the next digit (3) from the dividend after 61, then repeat: 613 / 171

Going ahead to step 7:
If we divide 613 by 171, we get 3 and a remainder of 100.
Use 3 as the next digit of our solution. 
Result so far: 51373.0
The remainder is 100 after subtracting 513 from 613.
Include the next digit (5) from the dividend after 100, then repeat: 1005 / 171

Advancing to step 8:
171 can be fit into 1005 5 times, resulting in a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 513735.0
Subtracting 855 from 1005 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 9:
1500 divided by 171 is 8 with a remainder of 132.
Use 8 as the next digit of our solution. 
Result so far: 513735.8
The remainder is 132 after subtracting 1368 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 10:
171 goes into 1320 7 times with a remainder of 123.
Write down 7 as next digit of the result. 
Result so far: 513735.87
Subtracting 1197 from 1320 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 11:
When dividing 1230 by 171, we get 7 with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 513735.877
Subtract 1197 from 1230 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final result is 513735.877 with a remainder of 0.0033.
