We're dividing 87009928 by 142 
Let's see how many times 142 fits into 87009928.

Advancing to step 1:
When dividing 8 by 142, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 142

Moving on to step 2:
87 divided by 142 is 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Grab the next digit (0) from the dividend, add it to 87, then carry on: 870 / 142

Going ahead to step 3:
If we divide 870 by 142, we get 6 and a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 852 from 870 and we're left with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 142

Step 4:
180 divided by 142 is 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtracting 142 from 180 leaves us with 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 142

Let's proceed to step 5:
The number 142 fits into 389 2 times, leaving a remainder of 105.
Put 2 as the next digit of the answer. 
Result so far: 612.0
Deduct 284 from 389 and we're left with 105.
Fetch the next digit (9) from the dividend, attach it to 105 and continue: 1059 / 142

Advancing to step 6:
1059 divided by 142 is 7 with a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 6127.0
Subtract 994 from 1059 to get 65.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 142

Let's proceed to step 7:
The number 142 fits into 652 4 times, leaving a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 61274.0
Subtract 568 from 652 to get 84.
Append the next digit (8) from the dividend to 84 and continue with: 848 / 142

Going ahead to step 8:
142 goes into 848 5 times with a remainder of 138.
Write down 5 as next digit of the result. 
Result so far: 612745.0
Subtracting 710 from 848 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 9:
The number 142 fits into 1380 9 times, leaving a remainder of 102.
Record the quotient 9 as the next digit in the result. 
Result so far: 612745.9
The remainder is 102 after subtracting 1278 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 10:
If we divide 1020 by 142, we get 7 and a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 612745.97
Deduct 994 from 1020 and we're left 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.

Let's proceed to step 11:
If we divide 260 by 142, we get 1 and a remainder of 118.
Put 1 as the next digit of the answer. 
Result so far: 612745.971
If we subtract 142 from 260, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 12:
When dividing 1180 by 142, we get 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 612745.9718
Subtract 1136 from 1180 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
When dividing 440 by 142, we get 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 612745.97183
If we take 426 away from 440, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
If we divide 140 by 142, we get 0 and a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 612745.97183
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 15:
The number 142 fits into 1400 9 times, leaving a remainder of 122.
The next digit of our result is 9. 
Result so far: 612745.9718309
If we take 1278 away from 1400, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 16:
1220 divided by 142 is 8 with a remainder of 84.
The next digit of our result is 8. 
Result so far: 612745.97183098
Subtract 1136 from 1220 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 612745.97183098 with a remainder of 8.4e-08.
