77910230 divided by 451 
Our goal is to divide 77910230 by 451.

On to step 1:
451 goes into 7 0 times 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.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 451

Let's proceed to step 2:
451 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 451

Moving on to step 3:
If we divide 779 by 451, we get 1 and a remainder of 328.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 451 from 779 leaves us with 328.
Append the next digit (1) from the dividend to 328 and continue with: 3281 / 451

Moving on to step 4:
The number 451 fits into 3281 7 times, leaving a remainder of 124.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 3157 from 3281, we get 124.
Grab the next digit (0) from the dividend, add it to 124, then carry on: 1240 / 451

On to step 5:
451 goes into 1240 2 times with a remainder of 338.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
Deduct 902 from 1240 and we're left with 338.
Append the next digit (2) from the dividend to 338 and continue with: 3382 / 451

Going ahead to step 6:
451 goes into 3382 7 times with a remainder of 225.
Put 7 as the next digit of the answer. 
Result so far: 1727.0
Subtracting 3157 from 3382 leaves us with 225.
Bring next digit (3) of the dividend behind the 225 and repeat the process: 2253 / 451

Advancing to step 7:
If we divide 2253 by 451, we get 4 and a remainder of 449.
Write down 4 as next digit of the result. 
Result so far: 17274.0
Subtracting 1804 from 2253 leaves us with 449.
Include the next digit (0) from the dividend after 449, then repeat: 4490 / 451

Moving on to step 8:
451 can be fit into 4490 9 times, resulting in a remainder of 431.
Record the quotient 9 as the next digit in the result. 
Result so far: 172749.0
If we take 4059 away from 4490, we end up with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Moving on to step 9:
When dividing 4310 by 451, we get 9 with a remainder of 251.
Put 9 as the next digit of the answer. 
Result so far: 172749.9
If we take 4059 away from 4310, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Going ahead to step 10:
2510 divided by 451 is 5 with a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 172749.95
Subtracting 2255 from 2510 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 11:
The number 451 fits into 2550 5 times, leaving a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 172749.955
Subtract 2255 from 2550 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Our division results in 172749.955 with a remaining 0.0295.
