74626778 ÷ 816 
We want to figure out the number of times 74626778 can be divided by 816.

Going ahead to step 1:
When dividing 7 by 816, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 816

Advancing to step 2:
816 can be fit into 74 0 times, resulting in a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 816

Moving on to step 3:
816 can be fit into 746 0 times, resulting in a remainder of 746.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 746 to get 746.
Include the next digit (2) from the dividend after 746, then repeat: 7462 / 816

Moving on to step 4:
816 goes into 7462 9 times with a remainder of 118.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7344 from 7462, we get 118.
Append the next digit (6) from the dividend to 118 and continue with: 1186 / 816

Going ahead to step 5:
1186 divided by 816 is 1 with a remainder of 370.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Deduct 816 from 1186 and we're left with 370.
Include the next digit (7) from the dividend after 370, then repeat: 3707 / 816

Moving on to step 6:
If we divide 3707 by 816, we get 4 and a remainder of 443.
Write down 4 as next digit of the result. 
Result so far: 914.0
Subtract 3264 from 3707 to get 443.
Append the next digit (7) from the dividend to 443 and continue with: 4437 / 816

Advancing to step 7:
If we divide 4437 by 816, we get 5 and a remainder of 357.
Write down 5 as next digit of the result. 
Result so far: 9145.0
The remainder is 357 after subtracting 4080 from 4437.
Bring next digit (8) of the dividend behind the 357 and repeat the process: 3578 / 816

Let's proceed to step 8:
If we divide 3578 by 816, we get 4 and a remainder of 314.
Record the quotient 4 as the next digit in the result. 
Result so far: 91454.0
If we subtract 3264 from 3578, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 9:
The number 816 fits into 3140 3 times, leaving a remainder of 692.
Use 3 as the next digit of our solution. 
Result so far: 91454.3
The remainder is 692 after subtracting 2448 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Step 10:
816 can be fit into 6920 8 times, resulting in a remainder of 392.
The number 8 becomes the next digit in our result. 
Result so far: 91454.38
Subtracting 6528 from 6920 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 11:
The number 816 fits into 3920 4 times, leaving a remainder of 656.
Put 4 as the next digit of the answer. 
Result so far: 91454.384
Subtracting 3264 from 3920 leaves us with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Step 12:
6560 divided by 816 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 91454.3848
If we subtract 6528 from 6560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
320 divided by 816 is 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 91454.3848
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
816 goes into 3200 3 times with a remainder of 752.
The number 3 becomes the next digit in our result. 
Result so far: 91454.384803
Deduct 2448 from 3200 and we're left with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Advancing to step 15:
When dividing 7520 by 816, we get 9 with a remainder of 176.
Use 9 as the next digit of our solution. 
Result so far: 91454.3848039
If we subtract 7344 from 7520, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 16:
If we divide 1760 by 816, we get 2 and a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 91454.38480392
If we subtract 1632 from 1760, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Our division results in 91454.38480392 with a remaining 1.28e-07.
