We're dividing 83610101 by 321 
Our goal is to divide 83610101 by 321.

Step 1:
When dividing 8 by 321, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 321

On to step 2:
The number 321 fits into 83 0 times, leaving a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Grab the next digit (6) from the dividend, add it to 83, then carry on: 836 / 321

Going ahead to step 3:
321 goes into 836 2 times with a remainder of 194.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 642 from 836 and we're left with 194.
Fetch the next digit (1) from the dividend, attach it to 194 and continue: 1941 / 321

Going ahead to step 4:
1941 divided by 321 is 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 1926 away from 1941, we end up with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 321

Moving on to step 5:
150 divided by 321 is 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 260.0
Subtracting 0 from 150 leaves us with 150.
Append the next digit (1) from the dividend to 150 and continue with: 1501 / 321

On to step 6:
If we divide 1501 by 321, we get 4 and a remainder of 217.
The next digit of our result is 4. 
Result so far: 2604.0
If we subtract 1284 from 1501, we get 217.
Grab the next digit (0) from the dividend, add it to 217, then carry on: 2170 / 321

Moving on to step 7:
2170 divided by 321 is 6 with a remainder of 244.
Use 6 as the next digit of our solution. 
Result so far: 26046.0
Deduct 1926 from 2170 and we're left with 244.
Include the next digit (1) from the dividend after 244, then repeat: 2441 / 321

Let's proceed to step 8:
321 can be fit into 2441 7 times, resulting in a remainder of 194.
Put 7 as the next digit of the answer. 
Result so far: 260467.0
If we take 2247 away from 2441, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 9:
321 goes into 1940 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 260467.6
Subtract 1926 from 1940 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
The number 321 fits into 140 0 times, leaving a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 260467.6
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 11:
When dividing 1400 by 321, we get 4 with a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 260467.604
The remainder is 116 after subtracting 1284 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 12:
321 can be fit into 1160 3 times, resulting in a remainder of 197.
Record the quotient 3 as the next digit in the result. 
Result so far: 260467.6043
If we subtract 963 from 1160, we get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 13:
321 can be fit into 1970 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 260467.60436
Subtract 1926 from 1970 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
440 divided by 321 is 1 with a remainder of 119.
Use 1 as the next digit of our solution. 
Result so far: 260467.604361
The remainder is 119 after subtracting 321 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 15:
If we divide 1190 by 321, we get 3 and a remainder of 227.
The number 3 becomes the next digit in our result. 
Result so far: 260467.6043613
If we subtract 963 from 1190, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Going ahead to step 16:
321 goes into 2270 7 times with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 260467.60436137
Subtract 2247 from 2270 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Our division results in 260467.60436137 with a remaining 2.3e-08.
