We're dividing 401813 by 51 
We want to divide 401813 by 51.

Step 1:
4 divided by 51 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 51

Step 2:
40 divided by 51 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 51

Step 3:
51 can be fit into 401 7 times, resulting in a remainder of 44.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 357 from 401, we get 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 51

Let's proceed to step 4:
When dividing 448 by 51, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtract 408 from 448 to get 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 51

Step 5:
51 can be fit into 401 7 times, resulting in a remainder of 44.
The next digit of our result is 7. 
Result so far: 787.0
The remainder is 44 after subtracting 357 from 401.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 51

Step 6:
51 can be fit into 443 8 times, resulting in a remainder of 35.
The next digit of our result is 8. 
Result so far: 7878.0
If we take 408 away from 443, 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.

On to step 7:
350 divided by 51 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 7878.6
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.

Step 8:
When dividing 440 by 51, we get 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 7878.68
Deduct 408 from 440 and we're left 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 9:
51 can be fit into 320 6 times, resulting in a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 7878.686
Subtract 306 from 320 to 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 10:
The number 51 fits into 140 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 7878.6862
Deduct 102 from 140 and we're left 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.

Going ahead to step 11:
The number 51 fits into 380 7 times, leaving a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 7878.68627
Subtract 357 from 380 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
51 can be fit into 230 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 7878.686274
Deduct 204 from 230 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 13:
The number 51 fits into 260 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 7878.6862745
If we subtract 255 from 260, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
51 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 7878.6862745
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 7878.6862745 with a remainder of 5e-08.
