Let's divide 26123934 by 321
We want to divide 26123934 by 321.

On to step 1:
321 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 321

Advancing to step 2:
321 goes into 26 0 times with a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 321

Let's proceed to step 3:
261 divided by 321 is 0 with a remainder of 261.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 261 leaves us with 261.
Fetch the next digit (2) from the dividend, attach it to 261 and continue: 2612 / 321

Advancing to step 4:
321 goes into 2612 8 times with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 2568 away from 2612, we end up with 44.
Fetch the next digit (3) from the dividend, attach it to 44 and continue: 443 / 321

Advancing to step 5:
When dividing 443 by 321, we get 1 with a remainder of 122.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtract 321 from 443 to get 122.
Append the next digit (9) from the dividend to 122 and continue with: 1229 / 321

Step 6:
When dividing 1229 by 321, we get 3 with a remainder of 266.
Put 3 as the next digit of the answer. 
Result so far: 813.0
If we take 963 away from 1229, we end up with 266.
Bring next digit (3) of the dividend behind the 266 and repeat the process: 2663 / 321

Moving on to step 7:
The number 321 fits into 2663 8 times, leaving a remainder of 95.
The number 8 becomes the next digit in our result. 
Result so far: 8138.0
Subtract 2568 from 2663 to get 95.
Grab the next digit (4) from the dividend, add it to 95, then carry on: 954 / 321

On to step 8:
954 divided by 321 is 2 with a remainder of 312.
Use 2 as the next digit of our solution. 
Result so far: 81382.0
Deduct 642 from 954 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 9:
3120 divided by 321 is 9 with a remainder of 231.
Use 9 as the next digit of our solution. 
Result so far: 81382.9
If we take 2889 away from 3120, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 10:
The number 321 fits into 2310 7 times, leaving a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 81382.97
If we take 2247 away from 2310, we end up 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 11:
630 divided by 321 is 1 with a remainder of 309.
Put 1 as the next digit of the answer. 
Result so far: 81382.971
Subtract 321 from 630 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 12:
When dividing 3090 by 321, we get 9 with a remainder of 201.
The number 9 becomes the next digit in our result. 
Result so far: 81382.9719
Subtracting 2889 from 3090 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 13:
321 can be fit into 2010 6 times, resulting in a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 81382.97196
The remainder is 84 after subtracting 1926 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 14:
When dividing 840 by 321, we get 2 with a remainder of 198.
Record the quotient 2 as the next digit in the result. 
Result so far: 81382.971962
Subtracting 642 from 840 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 15:
321 goes into 1980 6 times with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 81382.9719626
Subtracting 1926 from 1980 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 16:
540 divided by 321 is 1 with a remainder of 219.
The next digit of our result is 1. 
Result so far: 81382.97196261
Subtract 321 from 540 to get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

After the division, we end up with 81382.97196261 and a remainder of 2.19e-07.
