142519 ÷ 79 
Our goal is to divide 142519 by 79.

Advancing to step 1:
79 goes into 1 0 times 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.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 79

Going ahead to step 2:
14 divided by 79 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 79

Going ahead to step 3:
142 divided by 79 is 1 with a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 79 from 142 leaves us with 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 79

Advancing to step 4:
When dividing 635 by 79, we get 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 632 away from 635, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 79

Advancing to step 5:
When dividing 31 by 79, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
Deduct 0 from 31 and we're left with 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 79

Step 6:
79 can be fit into 319 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 1804.0
If we subtract 316 from 319, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 79 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1804.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 79 is 3 with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 1804.03
Deduct 237 from 300 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 9:
When dividing 630 by 79, we get 7 with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 1804.037
If we subtract 553 from 630, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 10:
770 divided by 79 is 9 with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 1804.0379
If we subtract 711 from 770, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 11:
When dividing 590 by 79, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 1804.03797
If we take 553 away from 590, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 12:
The number 79 fits into 370 4 times, leaving a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 1804.037974
If we take 316 away from 370, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 13:
When dividing 540 by 79, we get 6 with a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 1804.0379746
If we take 474 away from 540, we end up 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.

On to step 14:
If we divide 660 by 79, we get 8 and a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 1804.03797468
If we take 632 away from 660, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 1804.03797468 with a remaining 2.8e-08.
