We divide 105545 by 87
The aim is to understand the frequency of 87 in 105545.

Step 1:
87 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 87

Moving on to step 2:
10 divided by 87 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 87

Advancing to step 3:
When dividing 105 by 87, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 87 from 105 leaves us with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 87

Let's proceed to step 4:
185 divided by 87 is 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 174 from 185 and we're left with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 87

Advancing to step 5:
When dividing 114 by 87, we get 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 121.0
Subtracting 87 from 114 leaves us with 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 87

Let's proceed to step 6:
87 can be fit into 275 3 times, resulting in a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 1213.0
Subtract 261 from 275 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 87 is 1 with a remainder of 53.
The next digit of our result is 1. 
Result so far: 1213.1
Deduct 87 from 140 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 8:
The number 87 fits into 530 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 1213.16
Deduct 522 from 530 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 87, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 1213.16
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
87 goes into 800 9 times with a remainder of 17.
The next digit of our result is 9. 
Result so far: 1213.1609
If we take 783 away from 800, we end up 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 11:
170 divided by 87 is 1 with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 1213.16091
Subtract 87 from 170 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 12:
87 goes into 830 9 times with a remainder of 47.
The next digit of our result is 9. 
Result so far: 1213.160919
The remainder is 47 after subtracting 783 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 13:
The number 87 fits into 470 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1213.1609195
Subtract 435 from 470 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
If we divide 350 by 87, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 1213.16091954
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.

Our division results in 1213.16091954 with a remaining 2e-09.
