We look at the division of 51055033 by 640 
Let's see how many times 640 fits into 51055033.

Let's proceed to step 1:
640 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 640

Going ahead to step 2:
The number 640 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 640

Let's proceed to step 3:
640 goes into 510 0 times with a remainder of 510.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 510 after subtracting 0 from 510.
Append the next digit (5) from the dividend to 510 and continue with: 5105 / 640

On to step 4:
When dividing 5105 by 640, we get 7 with a remainder of 625.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 4480 away from 5105, we end up with 625.
Append the next digit (5) from the dividend to 625 and continue with: 6255 / 640

On to step 5:
When dividing 6255 by 640, we get 9 with a remainder of 495.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Deduct 5760 from 6255 and we're left with 495.
Include the next digit (0) from the dividend after 495, then repeat: 4950 / 640

Step 6:
The number 640 fits into 4950 7 times, leaving a remainder of 470.
Use 7 as the next digit of our solution. 
Result so far: 797.0
Subtract 4480 from 4950 to get 470.
Take the next digit (3) from the dividend and append it to 470, then repeat: 4703 / 640

Moving on to step 7:
640 goes into 4703 7 times with a remainder of 223.
Use 7 as the next digit of our solution. 
Result so far: 7977.0
Deduct 4480 from 4703 and we're left with 223.
Include the next digit (3) from the dividend after 223, then repeat: 2233 / 640

On to step 8:
640 can be fit into 2233 3 times, resulting in a remainder of 313.
Put 3 as the next digit of the answer. 
Result so far: 79773.0
If we take 1920 away from 2233, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 9:
When dividing 3130 by 640, we get 4 with a remainder of 570.
The number 4 becomes the next digit in our result. 
Result so far: 79773.4
If we subtract 2560 from 3130, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

On to step 10:
5700 divided by 640 is 8 with a remainder of 580.
The next digit of our result is 8. 
Result so far: 79773.48
Subtracting 5120 from 5700 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 11:
640 goes into 5800 9 times with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 79773.489
Subtract 5760 from 5800 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
400 divided by 640 is 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 79773.489
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 13:
640 can be fit into 4000 6 times, resulting in a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 79773.48906
The remainder is 160 after subtracting 3840 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
If we divide 1600 by 640, we get 2 and a remainder of 320.
Use 2 as the next digit of our solution. 
Result so far: 79773.489062
If we subtract 1280 from 1600, 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 goes into 3200 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 79773.4890625
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.

On to step 16:
If we divide 0 by 640, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 79773.4890625
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 79773.4890625 with a balance of 0.0.
