We divide 627581 by 87
The aim is to understand the frequency of 87 in 627581.

On to step 1:
The number 87 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 87

On to step 2:
When dividing 62 by 87, we get 0 with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Fetch the next digit (7) from the dividend, attach it to 62 and continue: 627 / 87

On to step 3:
The number 87 fits into 627 7 times, leaving a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 18 after subtracting 609 from 627.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 87

Going ahead to step 4:
87 goes into 185 2 times with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 72.0
The remainder is 11 after subtracting 174 from 185.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 87

Advancing to step 5:
87 can be fit into 118 1 times, resulting in a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 721.0
The remainder is 31 after subtracting 87 from 118.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 87

Going ahead to step 6:
87 can be fit into 311 3 times, resulting in a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 7213.0
If we subtract 261 from 311, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
500 divided by 87 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 7213.5
Deduct 435 from 500 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 8:
The number 87 fits into 650 7 times, leaving a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 7213.57
Subtracting 609 from 650 leaves us 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.

Let's proceed to step 9:
When dividing 410 by 87, we get 4 with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 7213.574
Subtract 348 from 410 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
If we divide 620 by 87, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 7213.5747
If we subtract 609 from 620, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
When dividing 110 by 87, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 7213.57471
If we subtract 87 from 110, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
87 can be fit into 230 2 times, resulting in a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 7213.574712
Subtracting 174 from 230 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
87 can be fit into 560 6 times, resulting in a remainder of 38.
The next digit of our result is 6. 
Result so far: 7213.5747126
Deduct 522 from 560 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
87 goes into 380 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7213.57471264
If we subtract 348 from 380, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 7213.57471264 and a remainder of 3.2e-08.
