We're dividing 70991 by 64 
Our goal is to divide 70991 by 64.

Moving on to step 1:
7 divided by 64 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 64

On to step 2:
When dividing 70 by 64, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 6 after subtracting 64 from 70.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 64

Let's proceed to step 3:
If we divide 69 by 64, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 5 after subtracting 64 from 69.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 64

Step 4:
59 divided by 64 is 0 with a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
The remainder is 59 after subtracting 0 from 59.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 64

Advancing to step 5:
If we divide 591 by 64, we get 9 and a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 1109.0
If we subtract 576 from 591, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 6:
The number 64 fits into 150 2 times, leaving a remainder of 22.
The next digit of our result is 2. 
Result so far: 1109.2
Subtracting 128 from 150 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
When dividing 220 by 64, we get 3 with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 1109.23
If we subtract 192 from 220, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
If we divide 280 by 64, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 1109.234
The remainder is 24 after subtracting 256 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
64 can be fit into 240 3 times, resulting in a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 1109.2343
Subtract 192 from 240 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.

Step 10:
If we divide 480 by 64, we get 7 and a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 1109.23437
If we take 448 away from 480, we end up 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.

Going ahead to step 11:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1109.234375
The remainder is 0 after subtracting 320 from 320.
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 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1109.234375
Subtract 0 from 0 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 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1109.234375
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.

Our division results in 1109.234375 with a remaining 0.0.
