We're dividing 399420 by 93 
We want to divide 399420 by 93.

Moving on to step 1:
3 divided by 93 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 93

Advancing to step 2:
The number 93 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 93

Moving on to step 3:
93 can be fit into 399 4 times, resulting in a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 372 from 399 leaves us with 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 93

Let's proceed to step 4:
The number 93 fits into 274 2 times, leaving a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtract 186 from 274 to get 88.
Bring next digit (2) of the dividend behind the 88 and repeat the process: 882 / 93

Moving on to step 5:
The number 93 fits into 882 9 times, leaving a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 429.0
Subtract 837 from 882 to get 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 93

Going ahead to step 6:
When dividing 450 by 93, we get 4 with a remainder of 78.
The next digit of our result is 4. 
Result so far: 4294.0
If we subtract 372 from 450, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 7:
780 divided by 93 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 4294.8
Deduct 744 from 780 and we're left 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.

Going ahead to step 8:
93 can be fit into 360 3 times, resulting in a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 4294.83
The remainder is 81 after subtracting 279 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 9:
93 can be fit into 810 8 times, resulting in a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 4294.838
If we subtract 744 from 810, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
660 divided by 93 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 4294.8387
If we subtract 651 from 660, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
93 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 4294.8387
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
93 can be fit into 900 9 times, resulting in a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 4294.838709
Subtracting 837 from 900 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 13:
If we divide 630 by 93, we get 6 and a remainder of 72.
The next digit of our result is 6. 
Result so far: 4294.8387096
Subtract 558 from 630 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
93 goes into 720 7 times with a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 4294.83870967
Subtract 651 from 720 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Our division results in 4294.83870967 with a remaining 6.9e-08.
