Let's divide 80563942 by 315
We want to divide 80563942 by 315.

Let's proceed to step 1:
315 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 315

Let's proceed to step 2:
315 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (5) from the dividend to 80 and continue with: 805 / 315

Let's proceed to step 3:
315 can be fit into 805 2 times, resulting in a remainder of 175.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 630 from 805 and we're left with 175.
Take the next digit (6) from the dividend and append it to 175, then repeat: 1756 / 315

Let's proceed to step 4:
315 can be fit into 1756 5 times, resulting in a remainder of 181.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 1575 from 1756 and we're left with 181.
Bring next digit (3) of the dividend behind the 181 and repeat the process: 1813 / 315

On to step 5:
The number 315 fits into 1813 5 times, leaving a remainder of 238.
Write down 5 as next digit of the result. 
Result so far: 255.0
Subtracting 1575 from 1813 leaves us with 238.
Take the next digit (9) from the dividend and append it to 238, then repeat: 2389 / 315

Moving on to step 6:
315 goes into 2389 7 times with a remainder of 184.
Record the quotient 7 as the next digit in the result. 
Result so far: 2557.0
If we take 2205 away from 2389, we end up with 184.
Include the next digit (4) from the dividend after 184, then repeat: 1844 / 315

Step 7:
315 can be fit into 1844 5 times, resulting in a remainder of 269.
Put 5 as the next digit of the answer. 
Result so far: 25575.0
The remainder is 269 after subtracting 1575 from 1844.
Fetch the next digit (2) from the dividend, attach it to 269 and continue: 2692 / 315

Going ahead to step 8:
When dividing 2692 by 315, we get 8 with a remainder of 172.
Record the quotient 8 as the next digit in the result. 
Result so far: 255758.0
If we subtract 2520 from 2692, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 9:
The number 315 fits into 1720 5 times, leaving a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 255758.5
Subtracting 1575 from 1720 leaves us 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.

Moving on to step 10:
1450 divided by 315 is 4 with a remainder of 190.
The number 4 becomes the next digit in our result. 
Result so far: 255758.54
The remainder is 190 after subtracting 1260 from 1450.
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 11:
The number 315 fits into 1900 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 255758.546
The remainder is 10 after subtracting 1890 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
If we divide 100 by 315, we get 0 and a remainder of 100.
The next digit of our result is 0. 
Result so far: 255758.546
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
1000 divided by 315 is 3 with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 255758.54603
Deduct 945 from 1000 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 14:
315 goes into 550 1 times with a remainder of 235.
Use 1 as the next digit of our solution. 
Result so far: 255758.546031
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.

Step 15:
315 can be fit into 2350 7 times, resulting in a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 255758.5460317
Deduct 2205 from 2350 and we're left 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.

Going ahead to step 16:
The number 315 fits into 1450 4 times, leaving a remainder of 190.
Put 4 as the next digit of the answer. 
Result so far: 255758.54603174
Deduct 1260 from 1450 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final result is 255758.54603174 with a remainder of 1.9e-07.
