We're dividing 87475271 by 141 
The aim is to understand the frequency of 141 in 87475271.

Moving on to step 1:
141 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 141

On to step 2:
The number 141 fits into 87 0 times, leaving 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.
Fetch the next digit (4) from the dividend, attach it to 87 and continue: 874 / 141

Going ahead to step 3:
141 can be fit into 874 6 times, resulting in a remainder of 28.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 28 after subtracting 846 from 874.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 141

Step 4:
141 can be fit into 287 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 62.0
If we subtract 282 from 287, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 141

On to step 5:
141 can be fit into 55 0 times, resulting in a remainder of 55.
The next digit of our result is 0. 
Result so far: 620.0
Subtracting 0 from 55 leaves us with 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 141

Step 6:
141 can be fit into 552 3 times, resulting in a remainder of 129.
Record the quotient 3 as the next digit in the result. 
Result so far: 6203.0
Deduct 423 from 552 and we're left with 129.
Bring next digit (7) of the dividend behind the 129 and repeat the process: 1297 / 141

Going ahead to step 7:
141 can be fit into 1297 9 times, resulting in a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 62039.0
Subtracting 1269 from 1297 leaves us with 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 141

Moving on to step 8:
When dividing 281 by 141, we get 1 with a remainder of 140.
Use 1 as the next digit of our solution. 
Result so far: 620391.0
Deduct 141 from 281 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 9:
141 goes into 1400 9 times with a remainder of 131.
Write down 9 as next digit of the result. 
Result so far: 620391.9
If we subtract 1269 from 1400, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 10:
If we divide 1310 by 141, we get 9 and a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 620391.99
Deduct 1269 from 1310 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Our division results in 620391.99 with a remaining 0.041.
