We're dividing 51201825 by 731 
We want to divide 51201825 by 731.

Let's proceed to step 1:
When dividing 5 by 731, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 731

Step 2:
51 divided by 731 is 0 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 (2) from the dividend to 51 and continue with: 512 / 731

On to step 3:
The number 731 fits into 512 0 times, leaving a remainder of 512.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 512 leaves us with 512.
Grab the next digit (0) from the dividend, add it to 512, then carry on: 5120 / 731

On to step 4:
When dividing 5120 by 731, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 5117 from 5120 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 731

On to step 5:
The number 731 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 70.0
If we subtract 0 from 31, we get 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 731

Step 6:
When dividing 318 by 731, we get 0 with a remainder of 318.
Write down 0 as next digit of the result. 
Result so far: 700.0
If we subtract 0 from 318, we get 318.
Take the next digit (2) from the dividend and append it to 318, then repeat: 3182 / 731

Going ahead to step 7:
3182 divided by 731 is 4 with a remainder of 258.
Put 4 as the next digit of the answer. 
Result so far: 7004.0
The remainder is 258 after subtracting 2924 from 3182.
Include the next digit (5) from the dividend after 258, then repeat: 2585 / 731

On to step 8:
If we divide 2585 by 731, we get 3 and a remainder of 392.
Use 3 as the next digit of our solution. 
Result so far: 70043.0
The remainder is 392 after subtracting 2193 from 2585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 9:
731 can be fit into 3920 5 times, resulting in a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 70043.5
Deduct 3655 from 3920 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 10:
731 goes into 2650 3 times with a remainder of 457.
Put 3 as the next digit of the answer. 
Result so far: 70043.53
Deduct 2193 from 2650 and we're left with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Step 11:
When dividing 4570 by 731, we get 6 with a remainder of 184.
The number 6 becomes the next digit in our result. 
Result so far: 70043.536
The remainder is 184 after subtracting 4386 from 4570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 12:
If we divide 1840 by 731, we get 2 and a remainder of 378.
Put 2 as the next digit of the answer. 
Result so far: 70043.5362
Deduct 1462 from 1840 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 13:
If we divide 3780 by 731, we get 5 and a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 70043.53625
The remainder is 125 after subtracting 3655 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 14:
731 can be fit into 1250 1 times, resulting in a remainder of 519.
Record the quotient 1 as the next digit in the result. 
Result so far: 70043.536251
Deduct 731 from 1250 and we're left with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

On to step 15:
When dividing 5190 by 731, we get 7 with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 70043.5362517
If we subtract 5117 from 5190, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 16:
When dividing 730 by 731, we get 0 with a remainder of 730.
Record the quotient 0 as the next digit in the result. 
Result so far: 70043.5362517
If we subtract 0 from 730, we get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Our division results in 70043.5362517 with a remaining 7.3e-07.
