Let's divide 77584123 by 448
We want to figure out the number of times 77584123 can be divided by 448.

On to step 1:
448 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 448

Step 2:
448 goes into 77 0 times with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 448

Going ahead to step 3:
448 can be fit into 775 1 times, resulting in a remainder of 327.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 448 from 775 leaves us with 327.
Append the next digit (8) from the dividend to 327 and continue with: 3278 / 448

Going ahead to step 4:
448 can be fit into 3278 7 times, resulting in a remainder of 142.
The next digit of our result is 7. 
Result so far: 17.0
If we take 3136 away from 3278, we end up with 142.
Include the next digit (4) from the dividend after 142, then repeat: 1424 / 448

Step 5:
The number 448 fits into 1424 3 times, leaving a remainder of 80.
Put 3 as the next digit of the answer. 
Result so far: 173.0
If we subtract 1344 from 1424, we get 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 448

Going ahead to step 6:
448 goes into 801 1 times with a remainder of 353.
Put 1 as the next digit of the answer. 
Result so far: 1731.0
Deduct 448 from 801 and we're left with 353.
Append the next digit (2) from the dividend to 353 and continue with: 3532 / 448

Moving on to step 7:
448 goes into 3532 7 times with a remainder of 396.
Write down 7 as next digit of the result. 
Result so far: 17317.0
Subtracting 3136 from 3532 leaves us with 396.
Grab the next digit (3) from the dividend, add it to 396, then carry on: 3963 / 448

Let's proceed to step 8:
When dividing 3963 by 448, we get 8 with a remainder of 379.
The next digit of our result is 8. 
Result so far: 173178.0
The remainder is 379 after subtracting 3584 from 3963.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Step 9:
The number 448 fits into 3790 8 times, leaving a remainder of 206.
Record the quotient 8 as the next digit in the result. 
Result so far: 173178.8
Subtracting 3584 from 3790 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 10:
448 can be fit into 2060 4 times, resulting in a remainder of 268.
Use 4 as the next digit of our solution. 
Result so far: 173178.84
The remainder is 268 after subtracting 1792 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 11:
The number 448 fits into 2680 5 times, leaving a remainder of 440.
Write down 5 as next digit of the result. 
Result so far: 173178.845
Subtract 2240 from 2680 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
When dividing 4400 by 448, we get 9 with a remainder of 368.
The next digit of our result is 9. 
Result so far: 173178.8459
Deduct 4032 from 4400 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 13:
The number 448 fits into 3680 8 times, leaving a remainder of 96.
The next digit of our result is 8. 
Result so far: 173178.84598
If we take 3584 away from 3680, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 14:
The number 448 fits into 960 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 173178.845982
The remainder is 64 after subtracting 896 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 15:
448 goes into 640 1 times with a remainder of 192.
Use 1 as the next digit of our solution. 
Result so far: 173178.8459821
If we subtract 448 from 640, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 16:
When dividing 1920 by 448, we get 4 with a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 173178.84598214
Subtracting 1792 from 1920 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 173178.84598214, with a leftover of 1.28e-07.
