42405247 divided by 315 
We want to divide 42405247 by 315.

On to step 1:
315 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.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 315

Advancing to step 2:
42 divided by 315 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 315

Going ahead to step 3:
When dividing 424 by 315, we get 1 with a remainder of 109.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 315 from 424 leaves us with 109.
Fetch the next digit (0) from the dividend, attach it to 109 and continue: 1090 / 315

On to step 4:
The number 315 fits into 1090 3 times, leaving a remainder of 145.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 945 away from 1090, we end up with 145.
Take the next digit (5) from the dividend and append it to 145, then repeat: 1455 / 315

On to step 5:
315 goes into 1455 4 times with a remainder of 195.
Use 4 as the next digit of our solution. 
Result so far: 134.0
Subtracting 1260 from 1455 leaves us with 195.
Include the next digit (2) from the dividend after 195, then repeat: 1952 / 315

Let's proceed to step 6:
The number 315 fits into 1952 6 times, leaving a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 1346.0
If we take 1890 away from 1952, we end up with 62.
Grab the next digit (4) from the dividend, add it to 62, then carry on: 624 / 315

Advancing to step 7:
315 goes into 624 1 times with a remainder of 309.
Record the quotient 1 as the next digit in the result. 
Result so far: 13461.0
If we subtract 315 from 624, we get 309.
Fetch the next digit (7) from the dividend, attach it to 309 and continue: 3097 / 315

Advancing to step 8:
315 goes into 3097 9 times with a remainder of 262.
Use 9 as the next digit of our solution. 
Result so far: 134619.0
If we subtract 2835 from 3097, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 9:
315 goes into 2620 8 times with a remainder of 100.
Use 8 as the next digit of our solution. 
Result so far: 134619.8
The remainder is 100 after subtracting 2520 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 10:
315 can be fit into 1000 3 times, resulting in a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 134619.83
The remainder is 55 after subtracting 945 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
315 can be fit into 550 1 times, resulting in a remainder of 235.
Put 1 as the next digit of the answer. 
Result so far: 134619.831
Deduct 315 from 550 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 12:
The number 315 fits into 2350 7 times, leaving a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 134619.8317
If we take 2205 away from 2350, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 13:
The number 315 fits into 1450 4 times, leaving a remainder of 190.
Use 4 as the next digit of our solution. 
Result so far: 134619.83174
If we subtract 1260 from 1450, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 14:
The number 315 fits into 1900 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 134619.831746
Deduct 1890 from 1900 and we're left 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.

Step 15:
When dividing 100 by 315, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 134619.831746
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.

Let's proceed to step 16:
315 can be fit into 1000 3 times, resulting in a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 134619.83174603
The remainder is 55 after subtracting 945 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 134619.83174603 with a remainder of 5.5e-08.
