The number 142 fits into 1256 8 times, leaving a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 36098.0
Deduct 1136 from 1256 and we're left with 120.
Grab the next digit (7) from the dividend, add it to 120, then carry on: 1207 / 142

Going ahead to step 8:
142 goes into 1207 8 times with a remainder of 71.
Write down 8 as next digit of the result. 
Result so far: 360988.0
The remainder is 71 after subtracting 1136 from 1207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 9:
If we divide 710 by 142, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 360988.5
Subtract 710 from 710 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
142 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 360988.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
When dividing 0 by 142, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 360988.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 360988.5 with a remaining 0.0.
