We're dividing 401071 by 51 
We're looking to find how many times 51 goes into 401071.

Advancing to step 1:
51 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 51

Moving on to step 2:
51 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 51

On to step 3:
51 can be fit into 401 7 times, resulting in a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 357 from 401 to get 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 51

Advancing to step 4:
440 divided by 51 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
If we subtract 408 from 440, we get 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 51

Moving on to step 5:
51 can be fit into 327 6 times, resulting in a remainder of 21.
The next digit of our result is 6. 
Result so far: 786.0
Subtract 306 from 327 to get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 51

Advancing to step 6:
51 goes into 211 4 times with a remainder of 7.
The next digit of our result is 4. 
Result so far: 7864.0
Subtracting 204 from 211 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.

Let's proceed to step 7:
The number 51 fits into 70 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 7864.1
Deduct 51 from 70 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
190 divided by 51 is 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 7864.13
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
51 goes into 370 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 7864.137
The remainder is 13 after subtracting 357 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
51 can be fit into 130 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 7864.1372
The remainder is 28 after subtracting 102 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
The number 51 fits into 280 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 7864.13725
If we take 255 away from 280, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
250 divided by 51 is 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 7864.137254
Subtract 204 from 250 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 13:
51 goes into 460 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 7864.1372549
The remainder is 1 after subtracting 459 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7864.1372549
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 7864.1372549, with a leftover of 1e-08.
