Let's divide 817643 by 51
We're looking to find how many times 51 goes into 817643.

On to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
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

Going ahead to step 2:
If we divide 81 by 51, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 51 from 81 to get 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 51

On to step 3:
51 goes into 307 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 306 from 307 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 51

Going ahead to step 4:
When dividing 16 by 51, we get 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 160.0
If we subtract 0 from 16, we get 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 51

On to step 5:
51 can be fit into 164 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 1603.0
If we take 153 away from 164, we end up with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 51

On to step 6:
When dividing 113 by 51, we get 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 16032.0
If we subtract 102 from 113, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
51 goes into 110 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 16032.2
Subtracting 102 from 110 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
51 goes into 80 1 times with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 16032.21
If we subtract 51 from 80, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
When dividing 290 by 51, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 16032.215
If we take 255 away from 290, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 16032.2156
Subtracting 306 from 350 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
If we divide 440 by 51, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 16032.21568
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
When dividing 320 by 51, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 16032.215686
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
51 can be fit into 140 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 16032.2156862
The remainder is 38 after subtracting 102 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
If we divide 380 by 51, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 16032.21568627
If we take 357 away from 380, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

After the division, we end up with 16032.21568627 and a remainder of 2.3e-08.
