We divide 811951 by 51
We want to divide 811951 by 51.

Let's proceed to step 1:
51 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 51

Advancing to step 2:
The number 51 fits into 81 1 times, leaving a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 51 from 81 to get 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 51

Going ahead to step 3:
The number 51 fits into 301 5 times, leaving a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 255 from 301, we get 46.
Grab the next digit (9) from the dividend, add it to 46, then carry on: 469 / 51

On to step 4:
When dividing 469 by 51, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtracting 459 from 469 leaves us with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 51

Moving on to step 5:
When dividing 105 by 51, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 1592.0
Subtract 102 from 105 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 51

Going ahead to step 6:
51 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 15920.0
If we take 0 away from 31, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
When dividing 310 by 51, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 15920.6
Deduct 306 from 310 and we're left 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.

On to step 8:
51 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 15920.6
Deduct 0 from 40 and we're left 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.

Advancing to step 9:
If we divide 400 by 51, we get 7 and a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 15920.607
Subtracting 357 from 400 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
430 divided by 51 is 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 15920.6078
If we subtract 408 from 430, we 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 11:
The number 51 fits into 220 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 15920.60784
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.

Going ahead to step 12:
160 divided by 51 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 15920.607843
Subtracting 153 from 160 leaves us 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.

Moving on to step 13:
70 divided by 51 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 15920.6078431
If we subtract 51 from 70, we 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.

Let's proceed to step 14:
51 can be fit into 190 3 times, resulting in a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 15920.60784313
If we subtract 153 from 190, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final outcome is 15920.60784313, with a leftover of 3.7e-08.
