42705182 ÷ 345 
Our goal is to divide 42705182 by 345.

Moving on to step 1:
345 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 345

Moving on to step 2:
The number 345 fits into 42 0 times, leaving 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 (7) from the dividend to 42 and continue with: 427 / 345

Moving on to step 3:
If we divide 427 by 345, we get 1 and a remainder of 82.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 345 from 427 leaves us with 82.
Take the next digit (0) from the dividend and append it to 82, then repeat: 820 / 345

On to step 4:
345 can be fit into 820 2 times, resulting in a remainder of 130.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 690 from 820, we get 130.
Append the next digit (5) from the dividend to 130 and continue with: 1305 / 345

Going ahead to step 5:
345 goes into 1305 3 times with a remainder of 270.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Subtracting 1035 from 1305 leaves us with 270.
Take the next digit (1) from the dividend and append it to 270, then repeat: 2701 / 345

Let's proceed to step 6:
2701 divided by 345 is 7 with a remainder of 286.
The next digit of our result is 7. 
Result so far: 1237.0
The remainder is 286 after subtracting 2415 from 2701.
Include the next digit (8) from the dividend after 286, then repeat: 2868 / 345

Going ahead to step 7:
The number 345 fits into 2868 8 times, leaving a remainder of 108.
Put 8 as the next digit of the answer. 
Result so far: 12378.0
If we take 2760 away from 2868, we end up with 108.
Bring next digit (2) of the dividend behind the 108 and repeat the process: 1082 / 345

Step 8:
The number 345 fits into 1082 3 times, leaving a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 123783.0
Subtract 1035 from 1082 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 9:
345 can be fit into 470 1 times, resulting in a remainder of 125.
Put 1 as the next digit of the answer. 
Result so far: 123783.1
If we take 345 away from 470, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 10:
1250 divided by 345 is 3 with a remainder of 215.
Record the quotient 3 as the next digit in the result. 
Result so far: 123783.13
If we subtract 1035 from 1250, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 11:
When dividing 2150 by 345, we get 6 with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 123783.136
The remainder is 80 after subtracting 2070 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
If we divide 800 by 345, we get 2 and a remainder of 110.
The number 2 becomes the next digit in our result. 
Result so far: 123783.1362
Subtracting 690 from 800 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 13:
When dividing 1100 by 345, we get 3 with a remainder of 65.
Write down 3 as next digit of the result. 
Result so far: 123783.13623
The remainder is 65 after subtracting 1035 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 14:
650 divided by 345 is 1 with a remainder of 305.
Put 1 as the next digit of the answer. 
Result so far: 123783.136231
If we subtract 345 from 650, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 15:
345 goes into 3050 8 times with a remainder of 290.
The next digit of our result is 8. 
Result so far: 123783.1362318
The remainder is 290 after subtracting 2760 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 16:
345 can be fit into 2900 8 times, resulting in a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 123783.13623188
If we subtract 2760 from 2900, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 123783.13623188, and the remainder is 1.4e-07.
