Let's divide 51821442 by 723
We want to figure out the number of times 51821442 can be divided by 723.

On to step 1:
The number 723 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 723

Moving on to step 2:
723 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 723

Advancing to step 3:
518 divided by 723 is 0 with a remainder of 518.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 518, we end up with 518.
Fetch the next digit (2) from the dividend, attach it to 518 and continue: 5182 / 723

Going ahead to step 4:
The number 723 fits into 5182 7 times, leaving a remainder of 121.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 5061 from 5182 and we're left with 121.
Bring next digit (1) of the dividend behind the 121 and repeat the process: 1211 / 723

Step 5:
When dividing 1211 by 723, we get 1 with a remainder of 488.
Use 1 as the next digit of our solution. 
Result so far: 71.0
The remainder is 488 after subtracting 723 from 1211.
Fetch the next digit (4) from the dividend, attach it to 488 and continue: 4884 / 723

On to step 6:
If we divide 4884 by 723, we get 6 and a remainder of 546.
The next digit of our result is 6. 
Result so far: 716.0
If we subtract 4338 from 4884, we get 546.
Append the next digit (4) from the dividend to 546 and continue with: 5464 / 723

Moving on to step 7:
5464 divided by 723 is 7 with a remainder of 403.
Put 7 as the next digit of the answer. 
Result so far: 7167.0
Subtracting 5061 from 5464 leaves us with 403.
Include the next digit (2) from the dividend after 403, then repeat: 4032 / 723

Going ahead to step 8:
4032 divided by 723 is 5 with a remainder of 417.
Use 5 as the next digit of our solution. 
Result so far: 71675.0
The remainder is 417 after subtracting 3615 from 4032.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Moving on to step 9:
When dividing 4170 by 723, we get 5 with a remainder of 555.
The number 5 becomes the next digit in our result. 
Result so far: 71675.5
If we subtract 3615 from 4170, we get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Going ahead to step 10:
The number 723 fits into 5550 7 times, leaving a remainder of 489.
The next digit of our result is 7. 
Result so far: 71675.57
Subtracting 5061 from 5550 leaves us with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Let's proceed to step 11:
The number 723 fits into 4890 6 times, leaving a remainder of 552.
The number 6 becomes the next digit in our result. 
Result so far: 71675.576
The remainder is 552 after subtracting 4338 from 4890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 12:
5520 divided by 723 is 7 with a remainder of 459.
Put 7 as the next digit of the answer. 
Result so far: 71675.5767
The remainder is 459 after subtracting 5061 from 5520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Going ahead to step 13:
723 can be fit into 4590 6 times, resulting in a remainder of 252.
Use 6 as the next digit of our solution. 
Result so far: 71675.57676
Subtracting 4338 from 4590 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 14:
723 goes into 2520 3 times with a remainder of 351.
Write down 3 as next digit of the result. 
Result so far: 71675.576763
If we take 2169 away from 2520, we end up with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Going ahead to step 15:
723 can be fit into 3510 4 times, resulting in a remainder of 618.
Record the quotient 4 as the next digit in the result. 
Result so far: 71675.5767634
Deduct 2892 from 3510 and we're left with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Moving on to step 16:
6180 divided by 723 is 8 with a remainder of 396.
The number 8 becomes the next digit in our result. 
Result so far: 71675.57676348
Deduct 5784 from 6180 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

The quotient of the division is 71675.57676348, and the remainder is 3.96e-07.
