We look at the division of 73723063 by 123 
Let's see how many times 123 fits into 73723063.

Advancing to step 1:
The number 123 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 123

Going ahead to step 2:
The number 123 fits into 73 0 times, leaving a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 123

Going ahead to step 3:
123 goes into 737 5 times with a remainder of 122.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 122 after subtracting 615 from 737.
Append the next digit (2) from the dividend to 122 and continue with: 1222 / 123

Moving on to step 4:
The number 123 fits into 1222 9 times, leaving a remainder of 115.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
If we subtract 1107 from 1222, we get 115.
Grab the next digit (3) from the dividend, add it to 115, then carry on: 1153 / 123

Going ahead to step 5:
If we divide 1153 by 123, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 599.0
Subtract 1107 from 1153 to get 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 123

Advancing to step 6:
The number 123 fits into 460 3 times, leaving a remainder of 91.
The next digit of our result is 3. 
Result so far: 5993.0
If we take 369 away from 460, we end up with 91.
Take the next digit (6) from the dividend and append it to 91, then repeat: 916 / 123

Advancing to step 7:
The number 123 fits into 916 7 times, leaving a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 59937.0
Deduct 861 from 916 and we're left with 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 123

Going ahead to step 8:
If we divide 553 by 123, we get 4 and a remainder of 61.
The number 4 becomes the next digit in our result. 
Result so far: 599374.0
Deduct 492 from 553 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 9:
123 can be fit into 610 4 times, resulting in a remainder of 118.
Put 4 as the next digit of the answer. 
Result so far: 599374.4
Subtract 492 from 610 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 10:
123 goes into 1180 9 times with a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 599374.49
If we subtract 1107 from 1180, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 11:
123 can be fit into 730 5 times, resulting in a remainder of 115.
The number 5 becomes the next digit in our result. 
Result so far: 599374.495
Subtract 615 from 730 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 12:
123 can be fit into 1150 9 times, resulting in a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 599374.4959
Subtracting 1107 from 1150 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 13:
430 divided by 123 is 3 with a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 599374.49593
If we subtract 369 from 430, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 14:
123 can be fit into 610 4 times, resulting in a remainder of 118.
Use 4 as the next digit of our solution. 
Result so far: 599374.495934
Subtract 492 from 610 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 15:
When dividing 1180 by 123, we get 9 with a remainder of 73.
The next digit of our result is 9. 
Result so far: 599374.4959349
Subtract 1107 from 1180 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 16:
730 divided by 123 is 5 with a remainder of 115.
The next digit of our result is 5. 
Result so far: 599374.49593495
Subtracting 615 from 730 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

After the division, we end up with 599374.49593495 and a remainder of 1.15e-07.
