77781778 divided by 454 
We want to divide 77781778 by 454.

Let's proceed to step 1:
The number 454 fits into 7 0 times, leaving 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.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 454

Going ahead to step 2:
If we divide 77 by 454, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (7) from the dividend, add it to 77, then carry on: 777 / 454

Going ahead to step 3:
454 goes into 777 1 times with a remainder of 323.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 323 after subtracting 454 from 777.
Include the next digit (8) from the dividend after 323, then repeat: 3238 / 454

Going ahead to step 4:
If we divide 3238 by 454, we get 7 and a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 3178 from 3238 to get 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 454

Step 5:
The number 454 fits into 601 1 times, leaving a remainder of 147.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
Deduct 454 from 601 and we're left with 147.
Bring next digit (7) of the dividend behind the 147 and repeat the process: 1477 / 454

Let's proceed to step 6:
The number 454 fits into 1477 3 times, leaving a remainder of 115.
Write down 3 as next digit of the result. 
Result so far: 1713.0
The remainder is 115 after subtracting 1362 from 1477.
Bring next digit (7) of the dividend behind the 115 and repeat the process: 1157 / 454

Moving on to step 7:
454 can be fit into 1157 2 times, resulting in a remainder of 249.
The next digit of our result is 2. 
Result so far: 17132.0
If we subtract 908 from 1157, we get 249.
Bring next digit (8) of the dividend behind the 249 and repeat the process: 2498 / 454

Going ahead to step 8:
454 goes into 2498 5 times with a remainder of 228.
Write down 5 as next digit of the result. 
Result so far: 171325.0
The remainder is 228 after subtracting 2270 from 2498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 9:
2280 divided by 454 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 171325.5
If we subtract 2270 from 2280, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
454 goes into 100 0 times with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 171325.5
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
The number 454 fits into 1000 2 times, leaving a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 171325.502
The remainder is 92 after subtracting 908 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 12:
454 goes into 920 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 171325.5022
The remainder is 12 after subtracting 908 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 171325.5022 with a remainder of 0.00012.
