59990020 ÷ 778 
Our goal is to divide 59990020 by 778.

Moving on to step 1:
If we divide 5 by 778, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 778

On to step 2:
If we divide 59 by 778, we get 0 and a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 59 after subtracting 0 from 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 778

Let's proceed to step 3:
The number 778 fits into 599 0 times, leaving a remainder of 599.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 599, we get 599.
Take the next digit (9) from the dividend and append it to 599, then repeat: 5999 / 778

Let's proceed to step 4:
When dividing 5999 by 778, we get 7 with a remainder of 553.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 553 after subtracting 5446 from 5999.
Take the next digit (0) from the dividend and append it to 553, then repeat: 5530 / 778

Going ahead to step 5:
778 goes into 5530 7 times with a remainder of 84.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
If we take 5446 away from 5530, we end up with 84.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 778

Step 6:
778 goes into 840 1 times with a remainder of 62.
The next digit of our result is 1. 
Result so far: 771.0
Deduct 778 from 840 and we're left with 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 778

Let's proceed to step 7:
When dividing 622 by 778, we get 0 with a remainder of 622.
Write down 0 as next digit of the result. 
Result so far: 7710.0
Subtracting 0 from 622 leaves us with 622.
Include the next digit (0) from the dividend after 622, then repeat: 6220 / 778

On to step 8:
If we divide 6220 by 778, we get 7 and a remainder of 774.
The number 7 becomes the next digit in our result. 
Result so far: 77107.0
If we subtract 5446 from 6220, we get 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

On to step 9:
7740 divided by 778 is 9 with a remainder of 738.
The next digit of our result is 9. 
Result so far: 77107.9
Subtracting 7002 from 7740 leaves us with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Let's proceed to step 10:
The number 778 fits into 7380 9 times, leaving a remainder of 378.
Use 9 as the next digit of our solution. 
Result so far: 77107.99
Subtract 7002 from 7380 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The final result is 77107.99 with a remainder of 0.378.
