42156307 divided by 423 
We want to figure out the number of times 42156307 can be divided by 423.

Advancing to step 1:
If we divide 4 by 423, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 423

Let's proceed to step 2:
42 divided by 423 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 423

Advancing to step 3:
If we divide 421 by 423, we get 0 and a remainder of 421.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 421, we get 421.
Fetch the next digit (5) from the dividend, attach it to 421 and continue: 4215 / 423

Let's proceed to step 4:
4215 divided by 423 is 9 with a remainder of 408.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 3807 away from 4215, we end up with 408.
Bring next digit (6) of the dividend behind the 408 and repeat the process: 4086 / 423

Advancing to step 5:
4086 divided by 423 is 9 with a remainder of 279.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtracting 3807 from 4086 leaves us with 279.
Fetch the next digit (3) from the dividend, attach it to 279 and continue: 2793 / 423

Let's proceed to step 6:
423 goes into 2793 6 times with a remainder of 255.
The next digit of our result is 6. 
Result so far: 996.0
If we subtract 2538 from 2793, we get 255.
Take the next digit (0) from the dividend and append it to 255, then repeat: 2550 / 423

Let's proceed to step 7:
The number 423 fits into 2550 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 9966.0
Subtracting 2538 from 2550 leaves us with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 423

On to step 8:
423 goes into 127 0 times with a remainder of 127.
The next digit of our result is 0. 
Result so far: 99660.0
Deduct 0 from 127 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 9:
When dividing 1270 by 423, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 99660.3
Subtract 1269 from 1270 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
The number 423 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 99660.3
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
When dividing 100 by 423, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 99660.3
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 99660.3 with a balance of 0.01.
