Let's divide 123153 by 73
We're looking to find how many times 73 goes into 123153.

On to step 1:
When dividing 1 by 73, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 73

Step 2:
When dividing 12 by 73, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 73

Step 3:
If we divide 123 by 73, we get 1 and a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 73 away from 123, we end up with 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 73

Advancing to step 4:
501 divided by 73 is 6 with a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 438 away from 501, we end up with 63.
Take the next digit (5) from the dividend and append it to 63, then repeat: 635 / 73

Moving on to step 5:
When dividing 635 by 73, we get 8 with a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 168.0
Deduct 584 from 635 and we're left with 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 73

On to step 6:
When dividing 513 by 73, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 1687.0
Subtracting 511 from 513 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
73 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1687.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
If we divide 200 by 73, we get 2 and a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 1687.02
If we subtract 146 from 200, we get 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 9:
73 goes into 540 7 times with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 1687.027
Subtracting 511 from 540 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 10:
290 divided by 73 is 3 with a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 1687.0273
Subtracting 219 from 290 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 11:
710 divided by 73 is 9 with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 1687.02739
Subtract 657 from 710 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 12:
When dividing 530 by 73, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 1687.027397
Deduct 511 from 530 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
73 goes into 190 2 times with a remainder of 44.
The next digit of our result is 2. 
Result so far: 1687.0273972
If we subtract 146 from 190, we 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.

Going ahead to step 14:
The number 73 fits into 440 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 1687.02739726
Subtracting 438 from 440 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 1687.02739726 with a remaining 2e-09.
