We divide 39955329 by 123
Our goal is to divide 39955329 by 123.

Moving on to step 1:
The number 123 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 123

Let's proceed to step 2:
39 divided by 123 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 123

Advancing to step 3:
If we divide 399 by 123, we get 3 and a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 369 from 399 leaves us with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 123

Going ahead to step 4:
305 divided by 123 is 2 with a remainder of 59.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtract 246 from 305 to get 59.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 123

Moving on to step 5:
When dividing 595 by 123, we get 4 with a remainder of 103.
Write down 4 as next digit of the result. 
Result so far: 324.0
Deduct 492 from 595 and we're left with 103.
Take the next digit (3) from the dividend and append it to 103, then repeat: 1033 / 123

Going ahead to step 6:
123 goes into 1033 8 times with a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 3248.0
Subtracting 984 from 1033 leaves us with 49.
Append the next digit (2) from the dividend to 49 and continue with: 492 / 123

Let's proceed to step 7:
If we divide 492 by 123, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 32484.0
Deduct 492 from 492 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 123

Let's proceed to step 8:
123 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 324840.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
If we divide 90 by 123, we get 0 and a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 324840.0
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
If we divide 900 by 123, we get 7 and a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 324840.07
Deduct 861 from 900 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 11:
123 goes into 390 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 324840.073
If we subtract 369 from 390, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
When dividing 210 by 123, we get 1 with a remainder of 87.
Use 1 as the next digit of our solution. 
Result so far: 324840.0731
Subtract 123 from 210 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 13:
123 can be fit into 870 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 324840.07317
Subtract 861 from 870 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
123 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 324840.07317
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 15:
If we divide 900 by 123, we get 7 and a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 324840.0731707
If we subtract 861 from 900, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 16:
If we divide 390 by 123, we get 3 and a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 324840.07317073
If we take 369 away from 390, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 324840.07317073 with a balance of 2.1e-08.
