We look at the division of 990158 by 87 
Let's see how many times 87 fits into 990158.

On to step 1:
9 divided by 87 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 87

On to step 2:
When dividing 99 by 87, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 87 from 99 to get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 87

Step 3:
The number 87 fits into 120 1 times, leaving a remainder of 33.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 87 from 120 and we're left with 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 87

Let's proceed to step 4:
If we divide 331 by 87, we get 3 and a remainder of 70.
The next digit of our result is 3. 
Result so far: 113.0
If we take 261 away from 331, we end up with 70.
Take the next digit (5) from the dividend and append it to 70, then repeat: 705 / 87

Going ahead to step 5:
705 divided by 87 is 8 with a remainder of 9.
The next digit of our result is 8. 
Result so far: 1138.0
The remainder is 9 after subtracting 696 from 705.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 87

Moving on to step 6:
87 can be fit into 98 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 11381.0
If we subtract 87 from 98, 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.

Moving on to step 7:
87 goes into 110 1 times with a remainder of 23.
The next digit of our result is 1. 
Result so far: 11381.1
Deduct 87 from 110 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 8:
If we divide 230 by 87, we get 2 and a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 11381.12
If we subtract 174 from 230, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
87 can be fit into 560 6 times, resulting in a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 11381.126
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 10:
If we divide 380 by 87, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 11381.1264
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.

On to step 11:
87 goes into 320 3 times with a remainder of 59.
The next digit of our result is 3. 
Result so far: 11381.12643
Deduct 261 from 320 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 12:
When dividing 590 by 87, we get 6 with a remainder of 68.
The next digit of our result is 6. 
Result so far: 11381.126436
If we take 522 away from 590, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
If we divide 680 by 87, we get 7 and a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 11381.1264367
If we take 609 away from 680, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 14:
87 can be fit into 710 8 times, resulting in a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 11381.12643678
The remainder is 14 after subtracting 696 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 11381.12643678 with a remaining 1.4e-08.
