78778370 ÷ 366 
We want to divide 78778370 by 366.

Advancing to step 1:
The number 366 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 366

Moving on to step 2:
When dividing 78 by 366, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 366

Going ahead to step 3:
When dividing 787 by 366, we get 2 with a remainder of 55.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 732 from 787 and we're left with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 366

Step 4:
366 can be fit into 557 1 times, resulting in a remainder of 191.
The next digit of our result is 1. 
Result so far: 21.0
If we take 366 away from 557, we end up with 191.
Take the next digit (8) from the dividend and append it to 191, then repeat: 1918 / 366

Advancing to step 5:
When dividing 1918 by 366, we get 5 with a remainder of 88.
Use 5 as the next digit of our solution. 
Result so far: 215.0
If we subtract 1830 from 1918, we get 88.
Bring next digit (3) of the dividend behind the 88 and repeat the process: 883 / 366

Step 6:
If we divide 883 by 366, we get 2 and a remainder of 151.
The number 2 becomes the next digit in our result. 
Result so far: 2152.0
Deduct 732 from 883 and we're left with 151.
Append the next digit (7) from the dividend to 151 and continue with: 1517 / 366

Let's proceed to step 7:
The number 366 fits into 1517 4 times, leaving a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 21524.0
Deduct 1464 from 1517 and we're left with 53.
Fetch the next digit (0) from the dividend, attach it to 53 and continue: 530 / 366

Step 8:
If we divide 530 by 366, we get 1 and a remainder of 164.
The number 1 becomes the next digit in our result. 
Result so far: 215241.0
If we take 366 away from 530, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 9:
366 goes into 1640 4 times with a remainder of 176.
The next digit of our result is 4. 
Result so far: 215241.4
Subtracting 1464 from 1640 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 10:
When dividing 1760 by 366, we get 4 with a remainder of 296.
The next digit of our result is 4. 
Result so far: 215241.44
The remainder is 296 after subtracting 1464 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

After the division, we end up with 215241.44 and a remainder of 0.296.
