We look at the division of 81961557 by 448 
We're looking to find how many times 448 goes into 81961557.

Advancing to step 1:
If we divide 8 by 448, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 448

Step 2:
If we divide 81 by 448, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 448

Let's proceed to step 3:
448 goes into 819 1 times with a remainder of 371.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 371 after subtracting 448 from 819.
Grab the next digit (6) from the dividend, add it to 371, then carry on: 3716 / 448

Advancing to step 4:
448 can be fit into 3716 8 times, resulting in a remainder of 132.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 132 after subtracting 3584 from 3716.
Include the next digit (1) from the dividend after 132, then repeat: 1321 / 448

Moving on to step 5:
448 goes into 1321 2 times with a remainder of 425.
Put 2 as the next digit of the answer. 
Result so far: 182.0
The remainder is 425 after subtracting 896 from 1321.
Append the next digit (5) from the dividend to 425 and continue with: 4255 / 448

Moving on to step 6:
448 goes into 4255 9 times with a remainder of 223.
Put 9 as the next digit of the answer. 
Result so far: 1829.0
If we take 4032 away from 4255, we end up with 223.
Include the next digit (5) from the dividend after 223, then repeat: 2235 / 448

Advancing to step 7:
The number 448 fits into 2235 4 times, leaving a remainder of 443.
The next digit of our result is 4. 
Result so far: 18294.0
If we subtract 1792 from 2235, we get 443.
Append the next digit (7) from the dividend to 443 and continue with: 4437 / 448

Step 8:
448 can be fit into 4437 9 times, resulting in a remainder of 405.
Use 9 as the next digit of our solution. 
Result so far: 182949.0
If we subtract 4032 from 4437, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Moving on to step 9:
When dividing 4050 by 448, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 182949.9
If we take 4032 away from 4050, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
448 can be fit into 180 0 times, resulting in a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 182949.9
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
448 can be fit into 1800 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 182949.904
If we subtract 1792 from 1800, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
448 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 182949.904
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
448 goes into 800 1 times with a remainder of 352.
Record the quotient 1 as the next digit in the result. 
Result so far: 182949.90401
The remainder is 352 after subtracting 448 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 14:
When dividing 3520 by 448, we get 7 with a remainder of 384.
The number 7 becomes the next digit in our result. 
Result so far: 182949.904017
If we take 3136 away from 3520, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 15:
448 goes into 3840 8 times with a remainder of 256.
The next digit of our result is 8. 
Result so far: 182949.9040178
Subtract 3584 from 3840 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 16:
When dividing 2560 by 448, we get 5 with a remainder of 320.
Record the quotient 5 as the next digit in the result. 
Result so far: 182949.90401785
The remainder is 320 after subtracting 2240 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

After the division, we end up with 182949.90401785 and a remainder of 3.2e-07.
