Step 4:
448 goes into 965 2 times with a remainder of 69.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 69 after subtracting 896 from 965.
Include the next digit (3) from the dividend after 69, then repeat: 693 / 448

Going ahead to step 5:
693 divided by 448 is 1 with a remainder of 245.
The next digit of our result is 1. 
Result so far: 121.0
If we subtract 448 from 693, we get 245.
Append the next digit (1) from the dividend to 245 and continue with: 2451 / 448

On to step 6:
448 can be fit into 2451 5 times, resulting in a remainder of 211.
Write down 5 as next digit of the result. 
Result so far: 1215.0
Deduct 2240 from 2451 and we're left with 211.
Include the next digit (7) from the dividend after 211, then repeat: 2117 / 448

Advancing to step 7:
The number 448 fits into 2117 4 times, leaving a remainder of 325.
The next digit of our result is 4. 
Result so far: 12154.0
Subtract 1792 from 2117 to get 325.
Append the next digit (2) from the dividend to 325 and continue with: 3252 / 448

On to step 8:
When dividing 3252 by 448, we get 7 with a remainder of 116.
The number 7 becomes the next digit in our result. 
Result so far: 121547.0
Subtracting 3136 from 3252 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 9:
448 goes into 1160 2 times with a remainder of 264.
The number 2 becomes the next digit in our result. 
Result so far: 121547.2
Deduct 896 from 1160 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 10:
448 can be fit into 2640 5 times, resulting in a remainder of 400.
The next digit of our result is 5. 
Result so far: 121547.25
Subtracting 2240 from 2640 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 11:
448 can be fit into 4000 8 times, resulting in a remainder of 416.
Use 8 as the next digit of our solution. 
Result so far: 121547.258
Subtract 3584 from 4000 to get 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 12:
448 goes into 4160 9 times with a remainder of 128.
Record the quotient 9 as the next digit in the result. 
Result so far: 121547.2589
Subtracting 4032 from 4160 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.

Moving on to step 13:
448 can be fit into 1280 2 times, resulting in a remainder of 384.
Use 2 as the next digit of our solution. 
Result so far: 121547.25892
Subtract 896 from 1280 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 14:
The number 448 fits into 3840 8 times, leaving a remainder of 256.
Record the quotient 8 as the next digit in the result. 
Result so far: 121547.258928
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 15:
448 can be fit into 2560 5 times, resulting in a remainder of 320.
Use 5 as the next digit of our solution. 
Result so far: 121547.2589285
If we subtract 2240 from 2560, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 16:
448 goes into 3200 7 times with a remainder of 64.
The next digit of our result is 7. 
Result so far: 121547.25892857
Subtracting 3136 from 3200 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 121547.25892857 with a remaining 6.4e-08.
