Let's divide 67936453 by 321
We want to divide 67936453 by 321.

Step 1:
The number 321 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 321

Advancing to step 2:
When dividing 67 by 321, we get 0 with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 321

Let's proceed to step 3:
When dividing 679 by 321, we get 2 with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 642 from 679 to get 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 321

Step 4:
321 can be fit into 373 1 times, resulting in a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 321 from 373, we get 52.
Take the next digit (6) from the dividend and append it to 52, then repeat: 526 / 321

Going ahead to step 5:
When dividing 526 by 321, we get 1 with a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 211.0
Deduct 321 from 526 and we're left with 205.
Grab the next digit (4) from the dividend, add it to 205, then carry on: 2054 / 321

Step 6:
321 goes into 2054 6 times with a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 2116.0
Subtracting 1926 from 2054 leaves us with 128.
Fetch the next digit (5) from the dividend, attach it to 128 and continue: 1285 / 321

Step 7:
The number 321 fits into 1285 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 21164.0
If we subtract 1284 from 1285, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 321

Moving on to step 8:
321 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 211640.0
If we subtract 0 from 13, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
321 can be fit into 130 0 times, resulting in a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 211640.0
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
If we divide 1300 by 321, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 211640.04
If we take 1284 away from 1300, we end up 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.

Advancing to step 11:
321 can be fit into 160 0 times, resulting in a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 211640.04
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
1600 divided by 321 is 4 with a remainder of 316.
Put 4 as the next digit of the answer. 
Result so far: 211640.0404
Deduct 1284 from 1600 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 13:
When dividing 3160 by 321, we get 9 with a remainder of 271.
Use 9 as the next digit of our solution. 
Result so far: 211640.04049
Subtract 2889 from 3160 to get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Going ahead to step 14:
2710 divided by 321 is 8 with a remainder of 142.
Write down 8 as next digit of the result. 
Result so far: 211640.040498
If we subtract 2568 from 2710, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 15:
When dividing 1420 by 321, we get 4 with a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 211640.0404984
If we take 1284 away from 1420, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 16:
1360 divided by 321 is 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 211640.04049844
Subtracting 1284 from 1360 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 211640.04049844, with a leftover of 7.6e-08.
