We're dividing 90600356 by 240 
We want to divide 90600356 by 240.

Step 1:
When dividing 9 by 240, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 240

Moving on to step 2:
The number 240 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Take the next digit (6) from the dividend and append it to 90, then repeat: 906 / 240

Going ahead to step 3:
240 goes into 906 3 times with a remainder of 186.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 720 from 906 and we're left with 186.
Append the next digit (0) from the dividend to 186 and continue with: 1860 / 240

Step 4:
240 goes into 1860 7 times with a remainder of 180.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 1680 from 1860 and we're left with 180.
Fetch the next digit (0) from the dividend, attach it to 180 and continue: 1800 / 240

On to step 5:
If we divide 1800 by 240, we get 7 and a remainder of 120.
Write down 7 as next digit of the result. 
Result so far: 377.0
If we subtract 1680 from 1800, we get 120.
Append the next digit (3) from the dividend to 120 and continue with: 1203 / 240

Advancing to step 6:
240 goes into 1203 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 3775.0
If we take 1200 away from 1203, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 240

Advancing to step 7:
240 goes into 35 0 times with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 37750.0
The remainder is 35 after subtracting 0 from 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 240

Going ahead to step 8:
The number 240 fits into 356 1 times, leaving a remainder of 116.
Use 1 as the next digit of our solution. 
Result so far: 377501.0
Subtracting 240 from 356 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 9:
When dividing 1160 by 240, we get 4 with a remainder of 200.
Put 4 as the next digit of the answer. 
Result so far: 377501.4
Deduct 960 from 1160 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
If we divide 2000 by 240, we get 8 and a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 377501.48
If we take 1920 away from 2000, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
240 can be fit into 800 3 times, resulting in a remainder of 80.
The next digit of our result is 3. 
Result so far: 377501.483
Deduct 720 from 800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
If we divide 800 by 240, we get 3 and a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 377501.4833
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 377501.4833 with a remainder of 0.0008.
