Let's divide 91341323 by 640
We want to divide 91341323 by 640.

Moving on to step 1:
640 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 640

Moving on to step 2:
The number 640 fits into 91 0 times, leaving a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Fetch the next digit (3) from the dividend, attach it to 91 and continue: 913 / 640

Step 3:
640 can be fit into 913 1 times, resulting in a remainder of 273.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 640 away from 913, we end up with 273.
Fetch the next digit (4) from the dividend, attach it to 273 and continue: 2734 / 640

Advancing to step 4:
640 goes into 2734 4 times with a remainder of 174.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2560 from 2734, we get 174.
Bring next digit (1) of the dividend behind the 174 and repeat the process: 1741 / 640

On to step 5:
If we divide 1741 by 640, we get 2 and a remainder of 461.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtracting 1280 from 1741 leaves us with 461.
Take the next digit (3) from the dividend and append it to 461, then repeat: 4613 / 640

Advancing to step 6:
When dividing 4613 by 640, we get 7 with a remainder of 133.
The next digit of our result is 7. 
Result so far: 1427.0
If we take 4480 away from 4613, we end up with 133.
Append the next digit (2) from the dividend to 133 and continue with: 1332 / 640

On to step 7:
640 can be fit into 1332 2 times, resulting in a remainder of 52.
The next digit of our result is 2. 
Result so far: 14272.0
The remainder is 52 after subtracting 1280 from 1332.
Include the next digit (3) from the dividend after 52, then repeat: 523 / 640

Advancing to step 8:
When dividing 523 by 640, we get 0 with a remainder of 523.
Record the quotient 0 as the next digit in the result. 
Result so far: 142720.0
Subtracting 0 from 523 leaves us with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Going ahead to step 9:
640 can be fit into 5230 8 times, resulting in a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 142720.8
Subtracting 5120 from 5230 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
If we divide 1100 by 640, we get 1 and a remainder of 460.
Write down 1 as next digit of the result. 
Result so far: 142720.81
If we subtract 640 from 1100, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
640 goes into 4600 7 times with a remainder of 120.
Use 7 as the next digit of our solution. 
Result so far: 142720.817
If we take 4480 away from 4600, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
1200 divided by 640 is 1 with a remainder of 560.
The next digit of our result is 1. 
Result so far: 142720.8171
The remainder is 560 after subtracting 640 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
640 goes into 5600 8 times with a remainder of 480.
The next digit of our result is 8. 
Result so far: 142720.81718
If we subtract 5120 from 5600, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 14:
640 goes into 4800 7 times with a remainder of 320.
Use 7 as the next digit of our solution. 
Result so far: 142720.817187
If we subtract 4480 from 4800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 15:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 142720.8171875
Deduct 3200 from 3200 and we're left 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:
If we divide 0 by 640, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 142720.8171875
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 142720.8171875 with a balance of 0.0.
