Let's divide 81249340 by 142
We want to divide 81249340 by 142.

Step 1:
142 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 142

Going ahead to step 2:
81 divided by 142 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 142

On to step 3:
If we divide 812 by 142, we get 5 and a remainder of 102.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 710 from 812, we get 102.
Include the next digit (4) from the dividend after 102, then repeat: 1024 / 142

Moving on to step 4:
142 goes into 1024 7 times with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 57.0
Subtract 994 from 1024 to get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 142

Going ahead to step 5:
142 goes into 309 2 times with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 572.0
Subtracting 284 from 309 leaves us with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 142

Advancing to step 6:
142 goes into 253 1 times with a remainder of 111.
Use 1 as the next digit of our solution. 
Result so far: 5721.0
Subtract 142 from 253 to get 111.
Bring next digit (4) of the dividend behind the 111 and repeat the process: 1114 / 142

Let's proceed to step 7:
142 goes into 1114 7 times with a remainder of 120.
The number 7 becomes the next digit in our result. 
Result so far: 57217.0
If we subtract 994 from 1114, we get 120.
Grab the next digit (0) from the dividend, add it to 120, then carry on: 1200 / 142

Advancing to step 8:
142 can be fit into 1200 8 times, resulting in a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 572178.0
Subtracting 1136 from 1200 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
If we divide 640 by 142, we get 4 and a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 572178.4
If we subtract 568 from 640, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
142 can be fit into 720 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 572178.45
Deduct 710 from 720 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
100 divided by 142 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 572178.45
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 12:
142 goes into 1000 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 572178.4507
If we take 994 away from 1000, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
If we divide 60 by 142, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 572178.4507
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
When dividing 600 by 142, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 572178.450704
If we subtract 568 from 600, 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 15:
320 divided by 142 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 572178.4507042
If we subtract 284 from 320, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 16:
142 goes into 360 2 times with a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 572178.45070422
Deduct 284 from 360 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 572178.45070422 and a remainder of 7.6e-08.
