83640 divided by 64 
We want to figure out the number of times 83640 can be divided by 64.

Going ahead to step 1:
If we divide 8 by 64, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 64

Advancing to step 2:
64 goes into 83 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 19 after subtracting 64 from 83.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 64

On to step 3:
When dividing 196 by 64, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 192 from 196 and we're left with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 64

Moving on to step 4:
If we divide 44 by 64, we get 0 and a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
Subtract 0 from 44 to get 44.
Append the next digit (0) from the dividend to 44 and continue with: 440 / 64

Moving on to step 5:
If we divide 440 by 64, we get 6 and a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 1306.0
Deduct 384 from 440 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 6:
64 can be fit into 560 8 times, resulting in a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 1306.8
Subtract 512 from 560 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
When dividing 480 by 64, we get 7 with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 1306.87
Subtracting 448 from 480 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1306.875
Subtract 320 from 320 to 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.

Advancing to step 9:
If we divide 0 by 64, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 1306.875
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.

Advancing to step 10:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1306.875
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 1306.875, and the remainder is 0.0.
