79744515 ÷ 140 
Our goal is to divide 79744515 by 140.

On to step 1:
When dividing 7 by 140, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 140

Step 2:
The number 140 fits into 79 0 times, leaving a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Bring next digit (7) of the dividend behind the 79 and repeat the process: 797 / 140

Moving on to step 3:
140 can be fit into 797 5 times, resulting in a remainder of 97.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 700 away from 797, we end up with 97.
Append the next digit (4) from the dividend to 97 and continue with: 974 / 140

Advancing to step 4:
When dividing 974 by 140, we get 6 with a remainder of 134.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Deduct 840 from 974 and we're left with 134.
Grab the next digit (4) from the dividend, add it to 134, then carry on: 1344 / 140

Step 5:
140 can be fit into 1344 9 times, resulting in a remainder of 84.
The next digit of our result is 9. 
Result so far: 569.0
Subtracting 1260 from 1344 leaves us with 84.
Bring next digit (5) of the dividend behind the 84 and repeat the process: 845 / 140

Going ahead to step 6:
140 goes into 845 6 times with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 5696.0
If we subtract 840 from 845, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 140

Going ahead to step 7:
140 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 56960.0
If we subtract 0 from 51, we get 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 140

Let's proceed to step 8:
If we divide 515 by 140, we get 3 and a remainder of 95.
The number 3 becomes the next digit in our result. 
Result so far: 569603.0
If we take 420 away from 515, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 9:
140 can be fit into 950 6 times, resulting in a remainder of 110.
Record the quotient 6 as the next digit in the result. 
Result so far: 569603.6
If we subtract 840 from 950, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
When dividing 1100 by 140, we get 7 with a remainder of 120.
The number 7 becomes the next digit in our result. 
Result so far: 569603.67
If we subtract 980 from 1100, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
140 goes into 1200 8 times with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 569603.678
If we subtract 1120 from 1200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
140 can be fit into 800 5 times, resulting in a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 569603.6785
Deduct 700 from 800 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 13:
When dividing 1000 by 140, we get 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 569603.67857
The remainder is 20 after subtracting 980 from 1000.
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 14:
The number 140 fits into 200 1 times, leaving a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 569603.678571
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
The number 140 fits into 600 4 times, leaving a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 569603.6785714
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 16:
If we divide 400 by 140, we get 2 and a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 569603.67857142
If we subtract 280 from 400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 569603.67857142 with a remaining 1.2e-07.
