We look at the division of 42904088 by 123 
Our goal is to divide 42904088 by 123.

Let's proceed to step 1:
123 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 123

Moving on to step 2:
If we divide 42 by 123, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 123

Moving on to step 3:
123 can be fit into 429 3 times, resulting in a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 369 from 429 and we're left with 60.
Include the next digit (0) from the dividend after 60, then repeat: 600 / 123

Advancing to step 4:
123 goes into 600 4 times with a remainder of 108.
The next digit of our result is 4. 
Result so far: 34.0
If we take 492 away from 600, we end up with 108.
Append the next digit (4) from the dividend to 108 and continue with: 1084 / 123

On to step 5:
123 goes into 1084 8 times with a remainder of 100.
Write down 8 as next digit of the result. 
Result so far: 348.0
The remainder is 100 after subtracting 984 from 1084.
Append the next digit (0) from the dividend to 100 and continue with: 1000 / 123

Advancing to step 6:
When dividing 1000 by 123, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3488.0
Subtracting 984 from 1000 leaves us with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 123

Going ahead to step 7:
123 can be fit into 168 1 times, resulting in a remainder of 45.
The next digit of our result is 1. 
Result so far: 34881.0
Subtracting 123 from 168 leaves us with 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 123

Moving on to step 8:
If we divide 458 by 123, we get 3 and a remainder of 89.
Record the quotient 3 as the next digit in the result. 
Result so far: 348813.0
Subtracting 369 from 458 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 9:
The number 123 fits into 890 7 times, leaving a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 348813.7
If we subtract 861 from 890, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 10:
123 can be fit into 290 2 times, resulting in a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 348813.72
Deduct 246 from 290 and we're left with 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 11:
The number 123 fits into 440 3 times, leaving a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 348813.723
The remainder is 71 after subtracting 369 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 12:
When dividing 710 by 123, we get 5 with a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 348813.7235
Deduct 615 from 710 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 13:
123 can be fit into 950 7 times, resulting in a remainder of 89.
The number 7 becomes the next digit in our result. 
Result so far: 348813.72357
Deduct 861 from 950 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 14:
890 divided by 123 is 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 348813.723577
If we take 861 away from 890, we end up 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.

The quotient of the division is 348813.723577, and the remainder is 2.9e-06.
