63870816 ÷ 235 
Our goal is to divide 63870816 by 235.

On to step 1:
235 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 235

Let's proceed to step 2:
63 divided by 235 is 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 235

Step 3:
When dividing 638 by 235, we get 2 with a remainder of 168.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 470 from 638, we get 168.
Grab the next digit (7) from the dividend, add it to 168, then carry on: 1687 / 235

Advancing to step 4:
235 goes into 1687 7 times with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtracting 1645 from 1687 leaves us with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 235

On to step 5:
The number 235 fits into 420 1 times, leaving a remainder of 185.
Use 1 as the next digit of our solution. 
Result so far: 271.0
If we take 235 away from 420, we end up with 185.
Grab the next digit (8) from the dividend, add it to 185, then carry on: 1858 / 235

Moving on to step 6:
1858 divided by 235 is 7 with a remainder of 213.
Write down 7 as next digit of the result. 
Result so far: 2717.0
The remainder is 213 after subtracting 1645 from 1858.
Take the next digit (1) from the dividend and append it to 213, then repeat: 2131 / 235

On to step 7:
The number 235 fits into 2131 9 times, leaving a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 27179.0
Subtracting 2115 from 2131 leaves us with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 235

Step 8:
If we divide 166 by 235, we get 0 and a remainder of 166.
The next digit of our result is 0. 
Result so far: 271790.0
If we subtract 0 from 166, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 9:
235 goes into 1660 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 271790.7
Subtract 1645 from 1660 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
When dividing 150 by 235, we get 0 with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 271790.7
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 11:
235 can be fit into 1500 6 times, resulting in a remainder of 90.
Write down 6 as next digit of the result. 
Result so far: 271790.706
Deduct 1410 from 1500 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 12:
235 can be fit into 900 3 times, resulting in a remainder of 195.
Put 3 as the next digit of the answer. 
Result so far: 271790.7063
If we take 705 away from 900, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 13:
1950 divided by 235 is 8 with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 271790.70638
Subtract 1880 from 1950 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 14:
235 can be fit into 700 2 times, resulting in a remainder of 230.
Record the quotient 2 as the next digit in the result. 
Result so far: 271790.706382
Subtracting 470 from 700 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 15:
If we divide 2300 by 235, we get 9 and a remainder of 185.
The next digit of our result is 9. 
Result so far: 271790.7063829
Subtracting 2115 from 2300 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 16:
The number 235 fits into 1850 7 times, leaving a remainder of 205.
Put 7 as the next digit of the answer. 
Result so far: 271790.70638297
The remainder is 205 after subtracting 1645 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The final outcome is 271790.70638297, with a leftover of 2.05e-07.
