We divide 141131 by 87
The aim is to understand the frequency of 87 in 141131.

Going ahead to step 1:
When dividing 1 by 87, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 87

Going ahead to step 2:
87 can be fit into 14 0 times, resulting in a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 87

Advancing to step 3:
If we divide 141 by 87, we get 1 and a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 87 from 141, we get 54.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 87

Let's proceed to step 4:
If we divide 541 by 87, we get 6 and a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 522 from 541, we get 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 87

On to step 5:
193 divided by 87 is 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
Subtracting 174 from 193 leaves us with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 87

Let's proceed to step 6:
If we divide 191 by 87, we get 2 and a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 1622.0
Deduct 174 from 191 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
87 goes into 170 1 times with a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 1622.1
Subtracting 87 from 170 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 8:
87 can be fit into 830 9 times, resulting in a remainder of 47.
The next digit of our result is 9. 
Result so far: 1622.19
Deduct 783 from 830 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 9:
When dividing 470 by 87, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1622.195
The remainder is 35 after subtracting 435 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
350 divided by 87 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 1622.1954
If we take 348 away from 350, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
The number 87 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1622.1954
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
When dividing 200 by 87, we get 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 1622.195402
Deduct 174 from 200 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
When dividing 260 by 87, we get 2 with a remainder of 86.
Write down 2 as next digit of the result. 
Result so far: 1622.1954022
The remainder is 86 after subtracting 174 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final outcome is 1622.1954022, with a leftover of 8.6e-07.
