Let's divide 800403 by 51
We want to divide 800403 by 51.

Moving on to step 1:
8 divided by 51 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 51

Going ahead to step 2:
51 goes into 80 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 51 from 80, we get 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 51

Going ahead to step 3:
When dividing 290 by 51, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 255 away from 290, we end up with 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 51

Advancing to step 4:
354 divided by 51 is 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Subtracting 306 from 354 leaves us with 48.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 51

Let's proceed to step 5:
When dividing 480 by 51, we get 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 1569.0
The remainder is 21 after subtracting 459 from 480.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 51

Advancing to step 6:
The number 51 fits into 213 4 times, leaving a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 15694.0
If we take 204 away from 213, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
51 goes into 90 1 times with a remainder of 39.
The next digit of our result is 1. 
Result so far: 15694.1
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 8:
The number 51 fits into 390 7 times, leaving a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 15694.17
Subtracting 357 from 390 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
330 divided by 51 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 15694.176
If we subtract 306 from 330, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
If we divide 240 by 51, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 15694.1764
If we take 204 away from 240, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
51 goes into 360 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 15694.17647
Subtracting 357 from 360 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
51 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 15694.17647
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
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: 15694.1764705
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
If we divide 450 by 51, we get 8 and a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 15694.17647058
Subtracting 408 from 450 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 15694.17647058 and a remainder of 4.2e-08.
