78445518 divided by 231 
Let's see how many times 231 fits into 78445518.

Going ahead to step 1:
If we divide 7 by 231, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 231

Advancing to step 2:
If we divide 78 by 231, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 231

Going ahead to step 3:
231 can be fit into 784 3 times, resulting in a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 693 from 784, we get 91.
Fetch the next digit (4) from the dividend, attach it to 91 and continue: 914 / 231

Advancing to step 4:
The number 231 fits into 914 3 times, leaving a remainder of 221.
The next digit of our result is 3. 
Result so far: 33.0
If we subtract 693 from 914, we get 221.
Take the next digit (5) from the dividend and append it to 221, then repeat: 2215 / 231

Step 5:
If we divide 2215 by 231, we get 9 and a remainder of 136.
Write down 9 as next digit of the result. 
Result so far: 339.0
Subtracting 2079 from 2215 leaves us with 136.
Bring next digit (5) of the dividend behind the 136 and repeat the process: 1365 / 231

Step 6:
The number 231 fits into 1365 5 times, leaving a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 3395.0
The remainder is 210 after subtracting 1155 from 1365.
Fetch the next digit (1) from the dividend, attach it to 210 and continue: 2101 / 231

On to step 7:
231 can be fit into 2101 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 33959.0
Deduct 2079 from 2101 and we're left with 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 231

Advancing to step 8:
If we divide 228 by 231, we get 0 and a remainder of 228.
Write down 0 as next digit of the result. 
Result so far: 339590.0
Deduct 0 from 228 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 9:
231 goes into 2280 9 times with a remainder of 201.
Put 9 as the next digit of the answer. 
Result so far: 339590.9
Subtract 2079 from 2280 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 10:
231 goes into 2010 8 times with a remainder of 162.
Use 8 as the next digit of our solution. 
Result so far: 339590.98
If we subtract 1848 from 2010, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 11:
The number 231 fits into 1620 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 339590.987
If we subtract 1617 from 1620, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
The number 231 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 339590.987
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
231 can be fit into 300 1 times, resulting in a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 339590.98701
The remainder is 69 after subtracting 231 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 14:
The number 231 fits into 690 2 times, leaving a remainder of 228.
Use 2 as the next digit of our solution. 
Result so far: 339590.987012
Deduct 462 from 690 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 15:
When dividing 2280 by 231, we get 9 with a remainder of 201.
Record the quotient 9 as the next digit in the result. 
Result so far: 339590.9870129
Deduct 2079 from 2280 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 16:
231 can be fit into 2010 8 times, resulting in a remainder of 162.
Use 8 as the next digit of our solution. 
Result so far: 339590.98701298
Subtracting 1848 from 2010 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The quotient of the division is 339590.98701298, and the remainder is 1.62e-07.
