8634321 ÷ 160 
We want to figure out the number of times 8634321 can be divided by 160.

Step 1:
The number 160 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 160

Step 2:
160 goes into 86 0 times with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Grab the next digit (3) from the dividend, add it to 86, then carry on: 863 / 160

Let's proceed to step 3:
If we divide 863 by 160, we get 5 and a remainder of 63.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 63 after subtracting 800 from 863.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 160

Going ahead to step 4:
634 divided by 160 is 3 with a remainder of 154.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtracting 480 from 634 leaves us with 154.
Take the next digit (3) from the dividend and append it to 154, then repeat: 1543 / 160

Advancing to step 5:
If we divide 1543 by 160, we get 9 and a remainder of 103.
Use 9 as the next digit of our solution. 
Result so far: 539.0
Deduct 1440 from 1543 and we're left with 103.
Include the next digit (2) from the dividend after 103, then repeat: 1032 / 160

Advancing to step 6:
160 goes into 1032 6 times with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 5396.0
Subtracting 960 from 1032 leaves us with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 160

Step 7:
The number 160 fits into 721 4 times, leaving a remainder of 81.
Write down 4 as next digit of the result. 
Result so far: 53964.0
Subtracting 640 from 721 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 8:
160 goes into 810 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 53964.5
Deduct 800 from 810 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
100 divided by 160 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 53964.5
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
160 can be fit into 1000 6 times, resulting in a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 53964.506
The remainder is 40 after subtracting 960 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
If we divide 400 by 160, we get 2 and a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 53964.5062
If we subtract 320 from 400, we 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.

Step 12:
If we divide 800 by 160, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 53964.50625
If we take 800 away from 800, 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 13:
The number 160 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 53964.50625
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.

Step 14:
When dividing 0 by 160, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 53964.50625
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.

The quotient of the division is 53964.50625, and the remainder is 0.0.
