We look at the division of 919451 by 87 
We want to figure out the number of times 919451 can be divided by 87.

Let's proceed to step 1:
87 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 87

Step 2:
87 goes into 91 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 87 from 91 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 87

Advancing to step 3:
49 divided by 87 is 0 with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 49 leaves us with 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 87

Let's proceed to step 4:
494 divided by 87 is 5 with a remainder of 59.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we subtract 435 from 494, we get 59.
Append the next digit (5) from the dividend to 59 and continue with: 595 / 87

Going ahead to step 5:
If we divide 595 by 87, we get 6 and a remainder of 73.
Use 6 as the next digit of our solution. 
Result so far: 1056.0
Subtract 522 from 595 to get 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 87

Advancing to step 6:
If we divide 731 by 87, we get 8 and a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 10568.0
Subtracting 696 from 731 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
When dividing 350 by 87, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 10568.4
Deduct 348 from 350 and we're left 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 8:
87 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 10568.4
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
If we divide 200 by 87, we get 2 and a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 10568.402
Subtracting 174 from 200 leaves us 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.

On to step 10:
The number 87 fits into 260 2 times, leaving a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 10568.4022
Deduct 174 from 260 and we're left with 86.
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 result is 10568.4022 with a remainder of 0.00086.
