We divide 393934 by 51
We want to divide 393934 by 51.

On to step 1:
51 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 51

Step 2:
If we divide 39 by 51, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 51

Advancing to step 3:
51 can be fit into 393 7 times, resulting in a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 357 from 393 and we're left with 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 51

Step 4:
51 can be fit into 369 7 times, resulting in a remainder of 12.
The next digit of our result is 7. 
Result so far: 77.0
Subtract 357 from 369 to get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 51

On to step 5:
When dividing 123 by 51, we get 2 with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 772.0
Deduct 102 from 123 and we're left with 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 51

Advancing to step 6:
51 goes into 214 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 7724.0
Deduct 204 from 214 and we're left 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.

Going ahead to step 7:
The number 51 fits into 100 1 times, leaving a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 7724.1
Subtracting 51 from 100 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 8:
If we divide 490 by 51, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 7724.19
Subtracting 459 from 490 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
If we divide 310 by 51, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 7724.196
The remainder is 4 after subtracting 306 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
51 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 7724.196
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
51 goes into 400 7 times with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 7724.19607
If we subtract 357 from 400, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 12:
430 divided by 51 is 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 7724.196078
Deduct 408 from 430 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
220 divided by 51 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 7724.1960784
Deduct 204 from 220 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
160 divided by 51 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 7724.19607843
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 7724.19607843, with a leftover of 7e-09.
