We're dividing 80642153 by 320 
We're looking to find how many times 320 goes into 80642153.

Let's proceed to step 1:
320 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
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 320

Going ahead to step 2:
320 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: 0.0
The remainder is 80 after subtracting 0 from 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 320

Step 3:
If we divide 806 by 320, we get 2 and a remainder of 166.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 640 from 806 leaves us with 166.
Include the next digit (4) from the dividend after 166, then repeat: 1664 / 320

Moving on to step 4:
320 goes into 1664 5 times with a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 1600 from 1664, we get 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 320

Moving on to step 5:
The number 320 fits into 642 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
If we subtract 640 from 642, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 320

Going ahead to step 6:
320 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 2520.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 320

Step 7:
320 can be fit into 215 0 times, resulting in a remainder of 215.
Write down 0 as next digit of the result. 
Result so far: 25200.0
Subtracting 0 from 215 leaves us with 215.
Take the next digit (3) from the dividend and append it to 215, then repeat: 2153 / 320

Advancing to step 8:
The number 320 fits into 2153 6 times, leaving a remainder of 233.
Record the quotient 6 as the next digit in the result. 
Result so far: 252006.0
If we take 1920 away from 2153, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 9:
320 goes into 2330 7 times with a remainder of 90.
Use 7 as the next digit of our solution. 
Result so far: 252006.7
If we take 2240 away from 2330, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
320 can be fit into 900 2 times, resulting in a remainder of 260.
The number 2 becomes the next digit in our result. 
Result so far: 252006.72
Subtract 640 from 900 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 11:
320 goes into 2600 8 times with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 252006.728
Subtract 2560 from 2600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
320 goes into 400 1 times with a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 252006.7281
Deduct 320 from 400 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
320 goes into 800 2 times with a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 252006.72812
Subtracting 640 from 800 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
When dividing 1600 by 320, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 252006.728125
If we take 1600 away from 1600, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
When dividing 0 by 320, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 252006.728125
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 16:
320 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 252006.728125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 252006.728125, with a leftover of 0.0.
