We're dividing 77285266 by 448 
We want to divide 77285266 by 448.

Advancing to step 1:
448 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of 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 / 448

Going ahead to step 2:
If we divide 77 by 448, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (2) from the dividend after 77, then repeat: 772 / 448

Step 3:
If we divide 772 by 448, we get 1 and a remainder of 324.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 448 from 772 to get 324.
Fetch the next digit (8) from the dividend, attach it to 324 and continue: 3248 / 448

Moving on to step 4:
448 can be fit into 3248 7 times, resulting in a remainder of 112.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 112 after subtracting 3136 from 3248.
Bring next digit (5) of the dividend behind the 112 and repeat the process: 1125 / 448

Going ahead to step 5:
If we divide 1125 by 448, we get 2 and a remainder of 229.
Use 2 as the next digit of our solution. 
Result so far: 172.0
Subtracting 896 from 1125 leaves us with 229.
Bring next digit (2) of the dividend behind the 229 and repeat the process: 2292 / 448

Advancing to step 6:
If we divide 2292 by 448, we get 5 and a remainder of 52.
Record the quotient 5 as the next digit in the result. 
Result so far: 1725.0
Subtract 2240 from 2292 to get 52.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 448

On to step 7:
448 can be fit into 526 1 times, resulting in a remainder of 78.
Put 1 as the next digit of the answer. 
Result so far: 17251.0
The remainder is 78 after subtracting 448 from 526.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 448

Advancing to step 8:
The number 448 fits into 786 1 times, leaving a remainder of 338.
The number 1 becomes the next digit in our result. 
Result so far: 172511.0
If we subtract 448 from 786, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 9:
448 goes into 3380 7 times with a remainder of 244.
Write down 7 as next digit of the result. 
Result so far: 172511.7
If we take 3136 away from 3380, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 10:
2440 divided by 448 is 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 172511.75
Subtracting 2240 from 2440 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
When dividing 2000 by 448, we get 4 with a remainder of 208.
The next digit of our result is 4. 
Result so far: 172511.754
If we subtract 1792 from 2000, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 12:
448 can be fit into 2080 4 times, resulting in a remainder of 288.
Record the quotient 4 as the next digit in the result. 
Result so far: 172511.7544
Subtracting 1792 from 2080 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 172511.7544, with a leftover of 0.00288.
