We're dividing 51611929 by 721 
We want to divide 51611929 by 721.

Moving on to step 1:
If we divide 5 by 721, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 721

Advancing to step 2:
When dividing 51 by 721, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 721

Going ahead to step 3:
If we divide 516 by 721, we get 0 and a remainder of 516.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 516, we get 516.
Include the next digit (1) from the dividend after 516, then repeat: 5161 / 721

On to step 4:
The number 721 fits into 5161 7 times, leaving a remainder of 114.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 5047 from 5161 to get 114.
Append the next digit (1) from the dividend to 114 and continue with: 1141 / 721

Let's proceed to step 5:
721 goes into 1141 1 times with a remainder of 420.
Use 1 as the next digit of our solution. 
Result so far: 71.0
The remainder is 420 after subtracting 721 from 1141.
Grab the next digit (9) from the dividend, add it to 420, then carry on: 4209 / 721

Let's proceed to step 6:
If we divide 4209 by 721, we get 5 and a remainder of 604.
Use 5 as the next digit of our solution. 
Result so far: 715.0
Subtracting 3605 from 4209 leaves us with 604.
Grab the next digit (2) from the dividend, add it to 604, then carry on: 6042 / 721

On to step 7:
721 can be fit into 6042 8 times, resulting in a remainder of 274.
Write down 8 as next digit of the result. 
Result so far: 7158.0
If we take 5768 away from 6042, we end up with 274.
Grab the next digit (9) from the dividend, add it to 274, then carry on: 2749 / 721

Advancing to step 8:
721 goes into 2749 3 times with a remainder of 586.
Put 3 as the next digit of the answer. 
Result so far: 71583.0
The remainder is 586 after subtracting 2163 from 2749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Moving on to step 9:
721 can be fit into 5860 8 times, resulting in a remainder of 92.
Record the quotient 8 as the next digit in the result. 
Result so far: 71583.8
If we take 5768 away from 5860, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
920 divided by 721 is 1 with a remainder of 199.
Use 1 as the next digit of our solution. 
Result so far: 71583.81
If we take 721 away from 920, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 11:
721 goes into 1990 2 times with a remainder of 548.
Use 2 as the next digit of our solution. 
Result so far: 71583.812
If we subtract 1442 from 1990, we get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

On to step 12:
The number 721 fits into 5480 7 times, leaving a remainder of 433.
Put 7 as the next digit of the answer. 
Result so far: 71583.8127
The remainder is 433 after subtracting 5047 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 13:
When dividing 4330 by 721, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 71583.81276
If we take 4326 away from 4330, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
721 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 71583.81276
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
When dividing 400 by 721, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 71583.81276
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 71583.81276 with a remaining 4e-06.
