70305145 ÷ 315 
We want to divide 70305145 by 315.

Let's proceed to step 1:
315 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 315

Moving on to step 2:
315 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 315

Let's proceed to step 3:
315 goes into 703 2 times with a remainder of 73.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 630 from 703, we get 73.
Include the next digit (0) from the dividend after 73, then repeat: 730 / 315

Going ahead to step 4:
315 can be fit into 730 2 times, resulting in a remainder of 100.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 630 from 730 leaves us with 100.
Bring next digit (5) of the dividend behind the 100 and repeat the process: 1005 / 315

Advancing to step 5:
315 goes into 1005 3 times with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 223.0
If we subtract 945 from 1005, we get 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 315

Advancing to step 6:
When dividing 601 by 315, we get 1 with a remainder of 286.
Record the quotient 1 as the next digit in the result. 
Result so far: 2231.0
Subtract 315 from 601 to get 286.
Grab the next digit (4) from the dividend, add it to 286, then carry on: 2864 / 315

On to step 7:
315 goes into 2864 9 times with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 22319.0
If we subtract 2835 from 2864, we get 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 315

Step 8:
295 divided by 315 is 0 with a remainder of 295.
The number 0 becomes the next digit in our result. 
Result so far: 223190.0
Subtracting 0 from 295 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 9:
If we divide 2950 by 315, we get 9 and a remainder of 115.
Write down 9 as next digit of the result. 
Result so far: 223190.9
If we take 2835 away from 2950, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 10:
The number 315 fits into 1150 3 times, leaving a remainder of 205.
Put 3 as the next digit of the answer. 
Result so far: 223190.93
The remainder is 205 after subtracting 945 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 11:
2050 divided by 315 is 6 with a remainder of 160.
The next digit of our result is 6. 
Result so far: 223190.936
If we subtract 1890 from 2050, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
If we divide 1600 by 315, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 223190.9365
The remainder is 25 after subtracting 1575 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
The number 315 fits into 250 0 times, leaving a remainder of 250.
The next digit of our result is 0. 
Result so far: 223190.9365
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 14:
If we divide 2500 by 315, we get 7 and a remainder of 295.
Use 7 as the next digit of our solution. 
Result so far: 223190.936507
The remainder is 295 after subtracting 2205 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 15:
When dividing 2950 by 315, we get 9 with a remainder of 115.
Write down 9 as next digit of the result. 
Result so far: 223190.9365079
Deduct 2835 from 2950 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 16:
The number 315 fits into 1150 3 times, leaving a remainder of 205.
Write down 3 as next digit of the result. 
Result so far: 223190.93650793
If we take 945 away from 1150, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The quotient of the division is 223190.93650793, and the remainder is 2.05e-07.
