We're dividing 83661712 by 448 
Our goal is to divide 83661712 by 448.

On to step 1:
448 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 448

Let's proceed to step 2:
448 can be fit into 83 0 times, resulting in a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Bring next digit (6) of the dividend behind the 83 and repeat the process: 836 / 448

Advancing to step 3:
836 divided by 448 is 1 with a remainder of 388.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 448 from 836 to get 388.
Grab the next digit (6) from the dividend, add it to 388, then carry on: 3886 / 448

Advancing to step 4:
3886 divided by 448 is 8 with a remainder of 302.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 302 after subtracting 3584 from 3886.
Grab the next digit (1) from the dividend, add it to 302, then carry on: 3021 / 448

Step 5:
448 goes into 3021 6 times with a remainder of 333.
The next digit of our result is 6. 
Result so far: 186.0
Subtracting 2688 from 3021 leaves us with 333.
Fetch the next digit (7) from the dividend, attach it to 333 and continue: 3337 / 448

Going ahead to step 6:
3337 divided by 448 is 7 with a remainder of 201.
Put 7 as the next digit of the answer. 
Result so far: 1867.0
Subtracting 3136 from 3337 leaves us with 201.
Fetch the next digit (1) from the dividend, attach it to 201 and continue: 2011 / 448

On to step 7:
When dividing 2011 by 448, we get 4 with a remainder of 219.
Record the quotient 4 as the next digit in the result. 
Result so far: 18674.0
If we subtract 1792 from 2011, we get 219.
Append the next digit (2) from the dividend to 219 and continue with: 2192 / 448

On to step 8:
If we divide 2192 by 448, we get 4 and a remainder of 400.
The number 4 becomes the next digit in our result. 
Result so far: 186744.0
If we subtract 1792 from 2192, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 9:
If we divide 4000 by 448, we get 8 and a remainder of 416.
Use 8 as the next digit of our solution. 
Result so far: 186744.8
Deduct 3584 from 4000 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 10:
448 can be fit into 4160 9 times, resulting in a remainder of 128.
Put 9 as the next digit of the answer. 
Result so far: 186744.89
Subtract 4032 from 4160 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 11:
448 goes into 1280 2 times with a remainder of 384.
The next digit of our result is 2. 
Result so far: 186744.892
Subtracting 896 from 1280 leaves us 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 12:
448 can be fit into 3840 8 times, resulting in a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 186744.8928
If we subtract 3584 from 3840, we 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.

Advancing to step 13:
The number 448 fits into 2560 5 times, leaving a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 186744.89285
Subtracting 2240 from 2560 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 14:
448 can be fit into 3200 7 times, resulting in a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 186744.892857
Subtract 3136 from 3200 to get 64.
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:
When dividing 640 by 448, we get 1 with a remainder of 192.
Use 1 as the next digit of our solution. 
Result so far: 186744.8928571
Subtracting 448 from 640 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 16:
When dividing 1920 by 448, we get 4 with a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 186744.89285714
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 186744.89285714, with a leftover of 1.28e-07.
