We look at the division of 721547 by 77 
Our goal is to divide 721547 by 77.

Step 1:
When dividing 7 by 77, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 77

On to step 2:
When dividing 72 by 77, we get 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 77

On to step 3:
When dividing 721 by 77, we get 9 with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 693 from 721 and we're left with 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 77

Advancing to step 4:
If we divide 285 by 77, we get 3 and a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we take 231 away from 285, we end up with 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 77

On to step 5:
77 can be fit into 544 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 937.0
Deduct 539 from 544 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 77

Step 6:
57 divided by 77 is 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 9370.0
If we take 0 away from 57, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 7:
77 can be fit into 570 7 times, resulting in a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 9370.7
Subtracting 539 from 570 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 8:
77 can be fit into 310 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 9370.74
Subtracting 308 from 310 leaves us 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 9:
20 divided by 77 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9370.74
The remainder is 20 after subtracting 0 from 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 10:
If we divide 200 by 77, we get 2 and a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 9370.7402
If we subtract 154 from 200, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
If we divide 460 by 77, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 9370.74025
If we take 385 away from 460, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 12:
77 goes into 750 9 times with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 9370.740259
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 13:
The number 77 fits into 570 7 times, leaving a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 9370.7402597
If we subtract 539 from 570, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 14:
77 can be fit into 310 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 9370.74025974
If we subtract 308 from 310, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 9370.74025974 and a remainder of 2e-09.
