We look at the division of 721371 by 77 
Let's see how many times 77 fits into 721371.

Moving on to step 1:
When dividing 7 by 77, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 77

Going ahead to step 2:
When dividing 72 by 77, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 77

Moving on to step 3:
721 divided by 77 is 9 with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 693 away from 721, we end up with 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 77

Advancing to step 4:
283 divided by 77 is 3 with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Deduct 231 from 283 and we're left with 52.
Take the next digit (7) from the dividend and append it to 52, then repeat: 527 / 77

Advancing to step 5:
When dividing 527 by 77, we get 6 with a remainder of 65.
Put 6 as the next digit of the answer. 
Result so far: 936.0
If we take 462 away from 527, we end up with 65.
Append the next digit (1) from the dividend to 65 and continue with: 651 / 77

Step 6:
77 goes into 651 8 times with a remainder of 35.
The next digit of our result is 8. 
Result so far: 9368.0
Subtract 616 from 651 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
When dividing 350 by 77, we get 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 9368.4
Subtract 308 from 350 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
77 goes into 420 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 9368.45
Subtract 385 from 420 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
350 divided by 77 is 4 with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 9368.454
The remainder is 42 after subtracting 308 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
When dividing 420 by 77, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 9368.4545
If we take 385 away from 420, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
When dividing 350 by 77, we get 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 9368.45454
Deduct 308 from 350 and we're left 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.

On to step 12:
The number 77 fits into 420 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 9368.454545
The remainder is 35 after subtracting 385 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
When dividing 350 by 77, we get 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 9368.4545454
The remainder is 42 after subtracting 308 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 14:
77 goes into 420 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 9368.45454545
The remainder is 35 after subtracting 385 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 9368.45454545, with a leftover of 3.5e-08.
