We're dividing 4137183 by 321 
We want to divide 4137183 by 321.

On to step 1:
When dividing 4 by 321, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 321

Moving on to step 2:
41 divided by 321 is 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Fetch the next digit (3) from the dividend, attach it to 41 and continue: 413 / 321

Let's proceed to step 3:
When dividing 413 by 321, we get 1 with a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 321 from 413 to get 92.
Append the next digit (7) from the dividend to 92 and continue with: 927 / 321

Advancing to step 4:
321 goes into 927 2 times with a remainder of 285.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 642 from 927 to get 285.
Bring next digit (1) of the dividend behind the 285 and repeat the process: 2851 / 321

On to step 5:
321 goes into 2851 8 times with a remainder of 283.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Subtracting 2568 from 2851 leaves us with 283.
Grab the next digit (8) from the dividend, add it to 283, then carry on: 2838 / 321

Moving on to step 6:
2838 divided by 321 is 8 with a remainder of 270.
The number 8 becomes the next digit in our result. 
Result so far: 1288.0
If we take 2568 away from 2838, we end up with 270.
Bring next digit (3) of the dividend behind the 270 and repeat the process: 2703 / 321

Moving on to step 7:
2703 divided by 321 is 8 with a remainder of 135.
The number 8 becomes the next digit in our result. 
Result so far: 12888.0
If we subtract 2568 from 2703, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 8:
321 can be fit into 1350 4 times, resulting in a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 12888.4
Deduct 1284 from 1350 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
The number 321 fits into 660 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 12888.42
If we subtract 642 from 660, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
If we divide 180 by 321, we get 0 and a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 12888.42
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
321 can be fit into 1800 5 times, resulting in a remainder of 195.
Record the quotient 5 as the next digit in the result. 
Result so far: 12888.4205
If we subtract 1605 from 1800, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 12:
321 can be fit into 1950 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 12888.42056
Deduct 1926 from 1950 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
When dividing 240 by 321, we get 0 with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 12888.42056
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 14:
When dividing 2400 by 321, we get 7 with a remainder of 153.
The number 7 becomes the next digit in our result. 
Result so far: 12888.4205607
The remainder is 153 after subtracting 2247 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 15:
If we divide 1530 by 321, we get 4 and a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 12888.42056074
Subtract 1284 from 1530 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

The quotient of the division is 12888.42056074, and the remainder is 2.46e-07.
