We're dividing 77913004 by 140 
We want to divide 77913004 by 140.

Moving on to step 1:
The number 140 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 140

Moving on to step 2:
140 goes into 77 0 times with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 140

Going ahead to step 3:
When dividing 779 by 140, we get 5 with a remainder of 79.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 700 away from 779, we end up with 79.
Take the next digit (1) from the dividend and append it to 79, then repeat: 791 / 140

Going ahead to step 4:
When dividing 791 by 140, we get 5 with a remainder of 91.
Put 5 as the next digit of the answer. 
Result so far: 55.0
If we take 700 away from 791, we end up with 91.
Grab the next digit (3) from the dividend, add it to 91, then carry on: 913 / 140

Going ahead to step 5:
If we divide 913 by 140, we get 6 and a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 556.0
Deduct 840 from 913 and we're left with 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 140

Step 6:
140 can be fit into 730 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5565.0
Subtract 700 from 730 to get 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 140

Advancing to step 7:
If we divide 300 by 140, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 55652.0
If we take 280 away from 300, we end up with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 140

On to step 8:
If we divide 204 by 140, we get 1 and a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 556521.0
Deduct 140 from 204 and we're left 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.

Step 9:
140 can be fit into 640 4 times, resulting in a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 556521.4
If we take 560 away from 640, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
800 divided by 140 is 5 with a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 556521.45
Subtract 700 from 800 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.

Going ahead to step 11:
The number 140 fits into 1000 7 times, leaving a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 556521.457
Subtracting 980 from 1000 leaves us 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.

Let's proceed to step 12:
140 can be fit into 200 1 times, resulting in a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 556521.4571
Deduct 140 from 200 and we're left 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.

On to step 13:
140 can be fit into 600 4 times, resulting in a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 556521.45714
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
The number 140 fits into 400 2 times, leaving a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 556521.457142
Subtracting 280 from 400 leaves us 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.

Advancing to step 15:
When dividing 1200 by 140, we get 8 with a remainder of 80.
The next digit of our result is 8. 
Result so far: 556521.4571428
If we take 1120 away from 1200, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
140 can be fit into 800 5 times, resulting in a remainder of 100.
The next digit of our result is 5. 
Result so far: 556521.45714285
If we take 700 away from 800, we end up 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.

After the division, we end up with 556521.45714285 and a remainder of 1e-07.
