We look at the division of 18393123 by 68 
We're looking to find how many times 68 goes into 18393123.

On to step 1:
If we divide 1 by 68, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 68

Moving on to step 2:
18 divided by 68 is 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 68

Step 3:
68 goes into 183 2 times with a remainder of 47.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 136 from 183 leaves us with 47.
Fetch the next digit (9) from the dividend, attach it to 47 and continue: 479 / 68

Going ahead to step 4:
479 divided by 68 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we subtract 476 from 479, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 68

On to step 5:
68 can be fit into 33 0 times, resulting in a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 270.0
Subtracting 0 from 33 leaves us with 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 68

On to step 6:
68 goes into 331 4 times with a remainder of 59.
The number 4 becomes the next digit in our result. 
Result so far: 2704.0
Subtract 272 from 331 to get 59.
Append the next digit (2) from the dividend to 59 and continue with: 592 / 68

Moving on to step 7:
When dividing 592 by 68, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 27048.0
Subtract 544 from 592 to get 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 68

Going ahead to step 8:
If we divide 483 by 68, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 270487.0
Deduct 476 from 483 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
If we divide 70 by 68, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 270487.1
Subtract 68 from 70 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
20 divided by 68 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 270487.1
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
The number 68 fits into 200 2 times, leaving a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 270487.102
Deduct 136 from 200 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
The number 68 fits into 640 9 times, leaving a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 270487.1029
Deduct 612 from 640 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
When dividing 280 by 68, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 270487.10294
The remainder is 8 after subtracting 272 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
If we divide 80 by 68, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 270487.102941
Subtract 68 from 80 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 15:
If we divide 120 by 68, we get 1 and a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 270487.1029411
Subtracting 68 from 120 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 270487.1029411 with a remainder of 5.2e-07.
