Let's divide 81070363 by 51
We want to divide 81070363 by 51.

Advancing to step 1:
The number 51 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 51

On to step 2:
The number 51 fits into 81 1 times, leaving a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 51 from 81 and we're left with 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 51

Going ahead to step 3:
51 can be fit into 300 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 45 after subtracting 255 from 300.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 51

Step 4:
457 divided by 51 is 8 with a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 158.0
Deduct 408 from 457 and we're left with 49.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 51

Step 5:
51 goes into 490 9 times with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 1589.0
Deduct 459 from 490 and we're left with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 51

Going ahead to step 6:
If we divide 313 by 51, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 15896.0
The remainder is 7 after subtracting 306 from 313.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 51

Let's proceed to step 7:
The number 51 fits into 76 1 times, leaving a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 158961.0
If we subtract 51 from 76, we get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 51

Let's proceed to step 8:
51 can be fit into 253 4 times, resulting in a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 1589614.0
The remainder is 49 after subtracting 204 from 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
490 divided by 51 is 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 1589614.9
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 10:
If we divide 310 by 51, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 1589614.96
Subtract 306 from 310 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
51 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1589614.96
The remainder is 40 after subtracting 0 from 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 12:
51 can be fit into 400 7 times, resulting in a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 1589614.9607
If we subtract 357 from 400, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 13:
51 goes into 430 8 times with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 1589614.96078
Subtract 408 from 430 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
51 can be fit into 220 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1589614.960784
Subtracting 204 from 220 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 15:
51 goes into 160 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 1589614.9607843
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 16:
If we divide 70 by 51, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1589614.96078431
Subtract 51 from 70 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 1589614.96078431 with a remainder of 1.9e-08.
