12410807 ÷ 142 
We want to divide 12410807 by 142.

On to step 1:
1 divided by 142 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 142

Moving on 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.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 142

Going ahead to step 3:
When dividing 124 by 142, we get 0 with a remainder of 124.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 124 leaves us with 124.
Bring next digit (1) of the dividend behind the 124 and repeat the process: 1241 / 142

Let's proceed to step 4:
1241 divided by 142 is 8 with a remainder of 105.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 1136 from 1241, we get 105.
Fetch the next digit (0) from the dividend, attach it to 105 and continue: 1050 / 142

Step 5:
If we divide 1050 by 142, we get 7 and a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we take 994 away from 1050, we end up with 56.
Fetch the next digit (8) from the dividend, attach it to 56 and continue: 568 / 142

Step 6:
If we divide 568 by 142, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 874.0
If we subtract 568 from 568, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 142

Let's proceed to step 7:
If we divide 0 by 142, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8740.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 142

Going ahead to step 8:
142 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 87400.0
If we subtract 0 from 7, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
The number 142 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 87400.0
If we subtract 0 from 70, we get 70.
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 10:
The number 142 fits into 700 4 times, leaving a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 87400.04
Subtract 568 from 700 to 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.

Going ahead to step 11:
When dividing 1320 by 142, we get 9 with a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 87400.049
Deduct 1278 from 1320 and we're left 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.

Step 12:
142 can be fit into 420 2 times, resulting in a remainder of 136.
Use 2 as the next digit of our solution. 
Result so far: 87400.0492
If we subtract 284 from 420, we get 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 13:
1360 divided by 142 is 9 with a remainder of 82.
The next digit of our result is 9. 
Result so far: 87400.04929
If we subtract 1278 from 1360, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 14:
If we divide 820 by 142, we get 5 and a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 87400.049295
The remainder is 110 after subtracting 710 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 15:
142 can be fit into 1100 7 times, resulting in a remainder of 106.
Write down 7 as next digit of the result. 
Result so far: 87400.0492957
If we subtract 994 from 1100, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 16:
142 can be fit into 1060 7 times, resulting in a remainder of 66.
The next digit of our result is 7. 
Result so far: 87400.04929577
Subtracting 994 from 1060 leaves us with 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 final outcome is 87400.04929577, with a leftover of 6.6e-08.
