We divide 55729674 by 640
Our goal is to divide 55729674 by 640.

Step 1:
When dividing 5 by 640, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 640

Step 2:
If we divide 55 by 640, we get 0 and a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Include the next digit (7) from the dividend after 55, then repeat: 557 / 640

Step 3:
The number 640 fits into 557 0 times, leaving a remainder of 557.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 557 to get 557.
Bring next digit (2) of the dividend behind the 557 and repeat the process: 5572 / 640

Moving on to step 4:
640 goes into 5572 8 times with a remainder of 452.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 5120 away from 5572, we end up with 452.
Append the next digit (9) from the dividend to 452 and continue with: 4529 / 640

Going ahead to step 5:
When dividing 4529 by 640, we get 7 with a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we take 4480 away from 4529, we end up with 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 640

On to step 6:
If we divide 496 by 640, we get 0 and a remainder of 496.
The number 0 becomes the next digit in our result. 
Result so far: 870.0
Subtracting 0 from 496 leaves us with 496.
Grab the next digit (7) from the dividend, add it to 496, then carry on: 4967 / 640

Let's proceed to step 7:
640 goes into 4967 7 times with a remainder of 487.
The next digit of our result is 7. 
Result so far: 8707.0
If we subtract 4480 from 4967, we get 487.
Append the next digit (4) from the dividend to 487 and continue with: 4874 / 640

Let's proceed to step 8:
If we divide 4874 by 640, we get 7 and a remainder of 394.
Record the quotient 7 as the next digit in the result. 
Result so far: 87077.0
Subtracting 4480 from 4874 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 9:
When dividing 3940 by 640, we get 6 with a remainder of 100.
Use 6 as the next digit of our solution. 
Result so far: 87077.6
The remainder is 100 after subtracting 3840 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
1000 divided by 640 is 1 with a remainder of 360.
Put 1 as the next digit of the answer. 
Result so far: 87077.61
If we subtract 640 from 1000, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 11:
The number 640 fits into 3600 5 times, leaving a remainder of 400.
The next digit of our result is 5. 
Result so far: 87077.615
If we subtract 3200 from 3600, we get 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 12:
When dividing 4000 by 640, we get 6 with a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 87077.6156
If we subtract 3840 from 4000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
When dividing 1600 by 640, we get 2 with a remainder of 320.
The next digit of our result is 2. 
Result so far: 87077.61562
Subtract 1280 from 1600 to 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 14:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 87077.615625
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.

Advancing to step 15:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 87077.615625
If we take 0 away from 0, 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.

Advancing to step 16:
0 divided by 640 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 87077.615625
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.

In conclusion, the division gives 87077.615625 with a balance of 0.0.
