Let's divide 800354 by 51
We want to figure out the number of times 800354 can be divided by 51.

Moving on to step 1:
8 divided by 51 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 51

Moving on to step 2:
51 goes into 80 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 51 from 80, we get 29.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 51

On to step 3:
If we divide 290 by 51, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 15.0
If we take 255 away from 290, we end up with 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 51

Moving on to step 4:
The number 51 fits into 353 6 times, leaving a remainder of 47.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
If we subtract 306 from 353, we get 47.
Take the next digit (5) from the dividend and append it to 47, then repeat: 475 / 51

Moving on to step 5:
51 goes into 475 9 times with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 1569.0
Subtract 459 from 475 to get 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 51

On to step 6:
When dividing 164 by 51, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 15693.0
Deduct 153 from 164 and we're left with 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:
The number 51 fits into 110 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 15693.2
Deduct 102 from 110 and we're left 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.

Moving on to step 8:
80 divided by 51 is 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 15693.21
Deduct 51 from 80 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
If we divide 290 by 51, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 15693.215
Subtracting 255 from 290 leaves us 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.

Going ahead to step 10:
If we divide 350 by 51, we get 6 and a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 15693.2156
The remainder is 44 after subtracting 306 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
440 divided by 51 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 15693.21568
Subtract 408 from 440 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
If we divide 320 by 51, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 15693.215686
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.

Going ahead to step 13:
When dividing 140 by 51, we get 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 15693.2156862
If we take 102 away from 140, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
If we divide 380 by 51, we get 7 and a remainder of 23.
The next digit of our result is 7. 
Result so far: 15693.21568627
Subtracting 357 from 380 leaves us 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.

The final result is 15693.21568627 with a remainder of 2.3e-08.
