3679872 ÷ 142 
Our goal is to divide 3679872 by 142.

Step 1:
The number 142 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 142

On to step 2:
142 goes into 36 0 times with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Append the next digit (7) from the dividend to 36 and continue with: 367 / 142

Advancing to step 3:
367 divided by 142 is 2 with a remainder of 83.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 284 from 367 and we're left with 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 142

Going ahead to step 4:
142 goes into 839 5 times with a remainder of 129.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 710 from 839 and we're left with 129.
Fetch the next digit (8) from the dividend, attach it to 129 and continue: 1298 / 142

Let's proceed to step 5:
142 can be fit into 1298 9 times, resulting in a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 259.0
Deduct 1278 from 1298 and we're left with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 142

Advancing to step 6:
If we divide 207 by 142, we get 1 and a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 2591.0
Subtract 142 from 207 to get 65.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 142

Moving on to step 7:
If we divide 652 by 142, we get 4 and a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 25914.0
If we subtract 568 from 652, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 8:
The number 142 fits into 840 5 times, leaving a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 25914.5
Subtracting 710 from 840 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 9:
If we divide 1300 by 142, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 25914.59
Subtract 1278 from 1300 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
When dividing 220 by 142, we get 1 with a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 25914.591
Subtracting 142 from 220 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 11:
142 can be fit into 780 5 times, resulting in a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 25914.5915
If we subtract 710 from 780, 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.

Moving on to step 12:
When dividing 700 by 142, we get 4 with a remainder of 132.
Record the quotient 4 as the next digit in the result. 
Result so far: 25914.59154
The remainder is 132 after subtracting 568 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 13:
The number 142 fits into 1320 9 times, leaving a remainder of 42.
The next digit of our result is 9. 
Result so far: 25914.591549
Subtracting 1278 from 1320 leaves us 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 14:
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: 25914.5915492
Subtract 284 from 420 to 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.

Step 15:
142 can be fit into 1360 9 times, resulting in a remainder of 82.
Record the quotient 9 as the next digit in the result. 
Result so far: 25914.59154929
Subtracting 1278 from 1360 leaves us 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.

The final outcome is 25914.59154929, with a leftover of 8.2e-08.
