We're dividing 76853942 by 448 
Our goal is to divide 76853942 by 448.

On to step 1:
448 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 448

Moving on to step 2:
The number 448 fits into 76 0 times, leaving a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 448

Advancing to step 3:
If we divide 768 by 448, we get 1 and a remainder of 320.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 448 from 768 and we're left with 320.
Grab the next digit (5) from the dividend, add it to 320, then carry on: 3205 / 448

On to step 4:
When dividing 3205 by 448, we get 7 with a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 3136 away from 3205, we end up with 69.
Fetch the next digit (3) from the dividend, attach it to 69 and continue: 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: 171.0
If we take 448 away from 693, we end up with 245.
Bring next digit (9) of the dividend behind the 245 and repeat the process: 2459 / 448

Going ahead to step 6:
When dividing 2459 by 448, we get 5 with a remainder of 219.
Put 5 as the next digit of the answer. 
Result so far: 1715.0
Subtract 2240 from 2459 to get 219.
Include the next digit (4) from the dividend after 219, then repeat: 2194 / 448

Let's proceed to step 7:
448 goes into 2194 4 times with a remainder of 402.
Write down 4 as next digit of the result. 
Result so far: 17154.0
If we take 1792 away from 2194, we end up with 402.
Bring next digit (2) of the dividend behind the 402 and repeat the process: 4022 / 448

Moving on to step 8:
448 goes into 4022 8 times with a remainder of 438.
Use 8 as the next digit of our solution. 
Result so far: 171548.0
Subtracting 3584 from 4022 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 9:
The number 448 fits into 4380 9 times, leaving a remainder of 348.
Record the quotient 9 as the next digit in the result. 
Result so far: 171548.9
The remainder is 348 after subtracting 4032 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 10:
448 can be fit into 3480 7 times, resulting in a remainder of 344.
Write down 7 as next digit of the result. 
Result so far: 171548.97
Deduct 3136 from 3480 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 11:
If we divide 3440 by 448, we get 7 and a remainder of 304.
Write down 7 as next digit of the result. 
Result so far: 171548.977
If we subtract 3136 from 3440, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final result is 171548.977 with a remainder of 0.0304.
