Let's divide 55397784 by 721
We want to divide 55397784 by 721.

On to step 1:
The number 721 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 721

Step 2:
55 divided by 721 is 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 721

Advancing to step 3:
If we divide 553 by 721, we get 0 and a remainder of 553.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 553 to get 553.
Fetch the next digit (9) from the dividend, attach it to 553 and continue: 5539 / 721

Advancing to step 4:
The number 721 fits into 5539 7 times, leaving a remainder of 492.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 5047 from 5539, we get 492.
Include the next digit (7) from the dividend after 492, then repeat: 4927 / 721

Let's proceed to step 5:
4927 divided by 721 is 6 with a remainder of 601.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtracting 4326 from 4927 leaves us with 601.
Grab the next digit (7) from the dividend, add it to 601, then carry on: 6017 / 721

Let's proceed to step 6:
The number 721 fits into 6017 8 times, leaving a remainder of 249.
The number 8 becomes the next digit in our result. 
Result so far: 768.0
Subtract 5768 from 6017 to get 249.
Grab the next digit (8) from the dividend, add it to 249, then carry on: 2498 / 721

Going ahead to step 7:
The number 721 fits into 2498 3 times, leaving a remainder of 335.
The next digit of our result is 3. 
Result so far: 7683.0
Subtracting 2163 from 2498 leaves us with 335.
Append the next digit (4) from the dividend to 335 and continue with: 3354 / 721

Advancing to step 8:
If we divide 3354 by 721, we get 4 and a remainder of 470.
Write down 4 as next digit of the result. 
Result so far: 76834.0
Subtract 2884 from 3354 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 9:
4700 divided by 721 is 6 with a remainder of 374.
The next digit of our result is 6. 
Result so far: 76834.6
The remainder is 374 after subtracting 4326 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 10:
721 goes into 3740 5 times with a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 76834.65
Deduct 3605 from 3740 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 11:
721 goes into 1350 1 times with a remainder of 629.
Put 1 as the next digit of the answer. 
Result so far: 76834.651
Deduct 721 from 1350 and we're left with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

On to step 12:
721 goes into 6290 8 times with a remainder of 522.
Write down 8 as next digit of the result. 
Result so far: 76834.6518
If we take 5768 away from 6290, we end up with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

On to step 13:
When dividing 5220 by 721, we get 7 with a remainder of 173.
Write down 7 as next digit of the result. 
Result so far: 76834.65187
Deduct 5047 from 5220 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 14:
The number 721 fits into 1730 2 times, leaving a remainder of 288.
Record the quotient 2 as the next digit in the result. 
Result so far: 76834.651872
Deduct 1442 from 1730 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 15:
2880 divided by 721 is 3 with a remainder of 717.
Put 3 as the next digit of the answer. 
Result so far: 76834.6518723
If we subtract 2163 from 2880, we get 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Advancing to step 16:
721 goes into 7170 9 times with a remainder of 681.
Use 9 as the next digit of our solution. 
Result so far: 76834.65187239
Subtracting 6489 from 7170 leaves us with 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

The final result is 76834.65187239 with a remainder of 6.81e-07.
