77699888 ÷ 454 
We're looking to find how many times 454 goes into 77699888.

Moving on to step 1:
7 divided by 454 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 454

Let's proceed to step 2:
If we divide 77 by 454, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 454

Moving on to step 3:
454 goes into 776 1 times with a remainder of 322.
The next digit of our result is 1. 
Result so far: 1.0
If we take 454 away from 776, we end up with 322.
Take the next digit (9) from the dividend and append it to 322, then repeat: 3229 / 454

Advancing to step 4:
The number 454 fits into 3229 7 times, leaving a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 3178 from 3229 to get 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 454

On to step 5:
When dividing 519 by 454, we get 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Subtracting 454 from 519 leaves us with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 454

On to step 6:
454 goes into 658 1 times with a remainder of 204.
The number 1 becomes the next digit in our result. 
Result so far: 1711.0
If we take 454 away from 658, we end up with 204.
Include the next digit (8) from the dividend after 204, then repeat: 2048 / 454

Advancing to step 7:
2048 divided by 454 is 4 with a remainder of 232.
The next digit of our result is 4. 
Result so far: 17114.0
Deduct 1816 from 2048 and we're left with 232.
Grab the next digit (8) from the dividend, add it to 232, then carry on: 2328 / 454

Step 8:
2328 divided by 454 is 5 with a remainder of 58.
The next digit of our result is 5. 
Result so far: 171145.0
The remainder is 58 after subtracting 2270 from 2328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
When dividing 580 by 454, we get 1 with a remainder of 126.
Use 1 as the next digit of our solution. 
Result so far: 171145.1
The remainder is 126 after subtracting 454 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 10:
454 can be fit into 1260 2 times, resulting in a remainder of 352.
The next digit of our result is 2. 
Result so far: 171145.12
If we subtract 908 from 1260, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 11:
If we divide 3520 by 454, we get 7 and a remainder of 342.
The next digit of our result is 7. 
Result so far: 171145.127
If we take 3178 away from 3520, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 12:
If we divide 3420 by 454, we get 7 and a remainder of 242.
Put 7 as the next digit of the answer. 
Result so far: 171145.1277
Subtracting 3178 from 3420 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Our division results in 171145.1277 with a remaining 0.00242.
