We look at the division of 25423849 by 142 
Our goal is to divide 25423849 by 142.

Moving on to step 1:
142 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 142

Let's proceed to step 2:
When dividing 25 by 142, we get 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 142

Step 3:
If we divide 254 by 142, we get 1 and a remainder of 112.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 112 after subtracting 142 from 254.
Grab the next digit (2) from the dividend, add it to 112, then carry on: 1122 / 142

Moving on to step 4:
If we divide 1122 by 142, we get 7 and a remainder of 128.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 128 after subtracting 994 from 1122.
Include the next digit (3) from the dividend after 128, then repeat: 1283 / 142

Advancing to step 5:
142 can be fit into 1283 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 179.0
Deduct 1278 from 1283 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 142

On to step 6:
142 goes into 58 0 times with a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 1790.0
If we subtract 0 from 58, we get 58.
Grab the next digit (4) from the dividend, add it to 58, then carry on: 584 / 142

Going ahead to step 7:
The number 142 fits into 584 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 17904.0
The remainder is 16 after subtracting 568 from 584.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 142

Advancing to step 8:
169 divided by 142 is 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 179041.0
Subtract 142 from 169 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
If we divide 270 by 142, we get 1 and a remainder of 128.
The number 1 becomes the next digit in our result. 
Result so far: 179041.1
The remainder is 128 after subtracting 142 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 10:
142 can be fit into 1280 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 179041.19
Deduct 1278 from 1280 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
The number 142 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 179041.19
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
If we divide 200 by 142, we get 1 and a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 179041.1901
Subtracting 142 from 200 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 13:
142 can be fit into 580 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 179041.19014
Deduct 568 from 580 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
When dividing 120 by 142, we get 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 179041.19014
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 15:
142 goes into 1200 8 times with a remainder of 64.
The next digit of our result is 8. 
Result so far: 179041.1901408
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.

Moving on to step 16:
142 can be fit into 640 4 times, resulting in a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 179041.19014084
The remainder is 72 after subtracting 568 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 179041.19014084, with a leftover of 7.2e-08.
