Let's divide 138640 by 64
Let's see how many times 64 fits into 138640.

Going ahead to step 1:
The number 64 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 64

On to step 2:
When dividing 13 by 64, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 64

On to step 3:
The number 64 fits into 138 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 128 from 138 to get 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 64

Moving on to step 4:
64 can be fit into 106 1 times, resulting in a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 64 from 106 to get 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 64

Step 5:
64 goes into 424 6 times with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 216.0
Subtracting 384 from 424 leaves us with 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 64

Step 6:
If we divide 400 by 64, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 2166.0
Deduct 384 from 400 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
160 divided by 64 is 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 2166.2
Subtracting 128 from 160 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.

Let's proceed to step 8:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2166.25
Subtracting 320 from 320 leaves us 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.

Let's proceed 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: 2166.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2166.25
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 result is 2166.25 with a remainder of 0.0.
