Let's divide 51136212 by 721
We want to divide 51136212 by 721.

Moving on to step 1:
If we divide 5 by 721, we get 0 and 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 (1) from the dividend, add it to 5, then carry on: 51 / 721

On to step 2:
When dividing 51 by 721, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 721

Let's proceed to step 3:
721 goes into 511 0 times with a remainder of 511.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 511 after subtracting 0 from 511.
Fetch the next digit (3) from the dividend, attach it to 511 and continue: 5113 / 721

Let's proceed to step 4:
721 goes into 5113 7 times with a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 66 after subtracting 5047 from 5113.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 721

Moving on to step 5:
666 divided by 721 is 0 with a remainder of 666.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
The remainder is 666 after subtracting 0 from 666.
Include the next digit (2) from the dividend after 666, then repeat: 6662 / 721

Moving on to step 6:
If we divide 6662 by 721, we get 9 and a remainder of 173.
Write down 9 as next digit of the result. 
Result so far: 709.0
Deduct 6489 from 6662 and we're left with 173.
Fetch the next digit (1) from the dividend, attach it to 173 and continue: 1731 / 721

Step 7:
721 goes into 1731 2 times with a remainder of 289.
The number 2 becomes the next digit in our result. 
Result so far: 7092.0
The remainder is 289 after subtracting 1442 from 1731.
Grab the next digit (2) from the dividend, add it to 289, then carry on: 2892 / 721

Going ahead to step 8:
721 goes into 2892 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 70924.0
The remainder is 8 after subtracting 2884 from 2892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
721 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 70924.0
Subtracting 0 from 80 leaves us 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.

Going ahead to step 10:
721 goes into 800 1 times with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 70924.01
Deduct 721 from 800 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 11:
721 goes into 790 1 times with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 70924.011
The remainder is 69 after subtracting 721 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

In conclusion, the division gives 70924.011 with a balance of 0.0069.
