12487124 ÷ 142 
We want to figure out the number of times 12487124 can be divided by 142.

Advancing to step 1:
142 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 142

Advancing to step 2:
The number 142 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 142

Let's proceed to step 3:
If we divide 124 by 142, we get 0 and a remainder of 124.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 124, we end up with 124.
Bring next digit (8) of the dividend behind the 124 and repeat the process: 1248 / 142

Going ahead to step 4:
142 can be fit into 1248 8 times, resulting in a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 112 after subtracting 1136 from 1248.
Fetch the next digit (7) from the dividend, attach it to 112 and continue: 1127 / 142

Advancing to step 5:
1127 divided by 142 is 7 with a remainder of 133.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Subtracting 994 from 1127 leaves us with 133.
Take the next digit (1) from the dividend and append it to 133, then repeat: 1331 / 142

Going ahead to step 6:
If we divide 1331 by 142, we get 9 and a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 879.0
Subtract 1278 from 1331 to get 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 142

Going ahead to step 7:
If we divide 532 by 142, we get 3 and a remainder of 106.
Use 3 as the next digit of our solution. 
Result so far: 8793.0
Subtract 426 from 532 to get 106.
Include the next digit (4) from the dividend after 106, then repeat: 1064 / 142

On to step 8:
1064 divided by 142 is 7 with a remainder of 70.
The next digit of our result is 7. 
Result so far: 87937.0
The remainder is 70 after subtracting 994 from 1064.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
142 can be fit into 700 4 times, resulting in a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 87937.4
If we subtract 568 from 700, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 10:
If we divide 1320 by 142, we get 9 and a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 87937.49
If we take 1278 away from 1320, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
When dividing 420 by 142, we get 2 with a remainder of 136.
The number 2 becomes the next digit in our result. 
Result so far: 87937.492
Deduct 284 from 420 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 12:
If we divide 1360 by 142, we get 9 and a remainder of 82.
The next digit of our result is 9. 
Result so far: 87937.4929
Deduct 1278 from 1360 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 13:
142 goes into 820 5 times with a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 87937.49295
Deduct 710 from 820 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 14:
142 goes into 1100 7 times with a remainder of 106.
Put 7 as the next digit of the answer. 
Result so far: 87937.492957
Deduct 994 from 1100 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 15:
If we divide 1060 by 142, we get 7 and a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 87937.4929577
Subtract 994 from 1060 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The quotient of the division is 87937.4929577, and the remainder is 6.6e-07.
