80059403 divided by 640 
Our goal is to divide 80059403 by 640.

Let's proceed to step 1:
If we divide 8 by 640, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 640

Going ahead to step 2:
640 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (0) from the dividend after 80, then repeat: 800 / 640

Advancing to step 3:
If we divide 800 by 640, we get 1 and a remainder of 160.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 640 from 800 to get 160.
Append the next digit (5) from the dividend to 160 and continue with: 1605 / 640

Let's proceed to step 4:
1605 divided by 640 is 2 with a remainder of 325.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 325 after subtracting 1280 from 1605.
Grab the next digit (9) from the dividend, add it to 325, then carry on: 3259 / 640

Step 5:
640 can be fit into 3259 5 times, resulting in a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
The remainder is 59 after subtracting 3200 from 3259.
Append the next digit (4) from the dividend to 59 and continue with: 594 / 640

Going ahead to step 6:
640 can be fit into 594 0 times, resulting in a remainder of 594.
Write down 0 as next digit of the result. 
Result so far: 1250.0
The remainder is 594 after subtracting 0 from 594.
Append the next digit (0) from the dividend to 594 and continue with: 5940 / 640

Moving on to step 7:
When dividing 5940 by 640, we get 9 with a remainder of 180.
Use 9 as the next digit of our solution. 
Result so far: 12509.0
Subtracting 5760 from 5940 leaves us with 180.
Include the next digit (3) from the dividend after 180, then repeat: 1803 / 640

Advancing to step 8:
640 goes into 1803 2 times with a remainder of 523.
Use 2 as the next digit of our solution. 
Result so far: 125092.0
Subtracting 1280 from 1803 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.

On to step 9:
The number 640 fits into 5230 8 times, leaving a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 125092.8
Subtract 5120 from 5230 to get 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.
Use 1 as the next digit of our solution. 
Result so far: 125092.81
If we take 640 away from 1100, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 11:
640 goes into 4600 7 times with a remainder of 120.
Write down 7 as next digit of the result. 
Result so far: 125092.817
Subtracting 4480 from 4600 leaves us 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:
If we divide 1200 by 640, we get 1 and a remainder of 560.
Put 1 as the next digit of the answer. 
Result so far: 125092.8171
Subtracting 640 from 1200 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 13:
If we divide 5600 by 640, we get 8 and a remainder of 480.
Put 8 as the next digit of the answer. 
Result so far: 125092.81718
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: 125092.817187
Subtracting 4480 from 4800 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 15:
When dividing 3200 by 640, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 125092.8171875
If we take 3200 away from 3200, 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.

Moving on to step 16:
If we divide 0 by 640, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 125092.8171875
Subtracting 0 from 0 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.

The final result is 125092.8171875 with a remainder of 0.0.
