Let's divide 56773787 by 721
Let's see how many times 721 fits into 56773787.

Advancing to step 1:
5 divided by 721 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 721

Going ahead to step 2:
721 can be fit into 56 0 times, resulting in a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Bring next digit (7) of the dividend behind the 56 and repeat the process: 567 / 721

Let's proceed to step 3:
When dividing 567 by 721, we get 0 with a remainder of 567.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 567 after subtracting 0 from 567.
Append the next digit (7) from the dividend to 567 and continue with: 5677 / 721

On to step 4:
5677 divided by 721 is 7 with a remainder of 630.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 630 after subtracting 5047 from 5677.
Bring next digit (3) of the dividend behind the 630 and repeat the process: 6303 / 721

On to step 5:
If we divide 6303 by 721, we get 8 and a remainder of 535.
The next digit of our result is 8. 
Result so far: 78.0
Deduct 5768 from 6303 and we're left with 535.
Append the next digit (7) from the dividend to 535 and continue with: 5357 / 721

Going ahead to step 6:
5357 divided by 721 is 7 with a remainder of 310.
The number 7 becomes the next digit in our result. 
Result so far: 787.0
Subtract 5047 from 5357 to get 310.
Grab the next digit (8) from the dividend, add it to 310, then carry on: 3108 / 721

Step 7:
The number 721 fits into 3108 4 times, leaving a remainder of 224.
Record the quotient 4 as the next digit in the result. 
Result so far: 7874.0
Deduct 2884 from 3108 and we're left with 224.
Append the next digit (7) from the dividend to 224 and continue with: 2247 / 721

Let's proceed to step 8:
When dividing 2247 by 721, we get 3 with a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 78743.0
Deduct 2163 from 2247 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 9:
721 can be fit into 840 1 times, resulting in a remainder of 119.
Put 1 as the next digit of the answer. 
Result so far: 78743.1
Subtracting 721 from 840 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 10:
The number 721 fits into 1190 1 times, leaving a remainder of 469.
Use 1 as the next digit of our solution. 
Result so far: 78743.11
Subtract 721 from 1190 to get 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

The final outcome is 78743.11, with a leftover of 0.469.
