912988 divided by 87 
Let's see how many times 87 fits into 912988.

Moving on to step 1:
9 divided by 87 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 87

Going ahead to step 2:
If we divide 91 by 87, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 87 from 91 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 87

Going ahead to step 3:
87 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 42, we end up with 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 87

On to step 4:
When dividing 429 by 87, we get 4 with a remainder of 81.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Subtract 348 from 429 to get 81.
Append the next digit (8) from the dividend to 81 and continue with: 818 / 87

Step 5:
When dividing 818 by 87, we get 9 with a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 1049.0
Deduct 783 from 818 and we're left with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 87

Let's proceed to step 6:
If we divide 358 by 87, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 10494.0
Deduct 348 from 358 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
When dividing 100 by 87, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 10494.1
If we take 87 away from 100, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
When dividing 130 by 87, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 10494.11
Subtract 87 from 130 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final result is 10494.11 with a remainder of 0.043.
