We look at the division of 5686991 by 640 
We're looking to find how many times 640 goes into 5686991.

Moving on to step 1:
5 divided by 640 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 640

Going ahead to step 2:
The number 640 fits into 56 0 times, leaving a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 640

Going ahead to step 3:
568 divided by 640 is 0 with a remainder of 568.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 568, we get 568.
Bring next digit (6) of the dividend behind the 568 and repeat the process: 5686 / 640

On to step 4:
The number 640 fits into 5686 8 times, leaving a remainder of 566.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 5120 from 5686 and we're left with 566.
Take the next digit (9) from the dividend and append it to 566, then repeat: 5669 / 640

Step 5:
The number 640 fits into 5669 8 times, leaving a remainder of 549.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
The remainder is 549 after subtracting 5120 from 5669.
Fetch the next digit (9) from the dividend, attach it to 549 and continue: 5499 / 640

Going ahead to step 6:
When dividing 5499 by 640, we get 8 with a remainder of 379.
The next digit of our result is 8. 
Result so far: 888.0
If we subtract 5120 from 5499, we get 379.
Bring next digit (1) of the dividend behind the 379 and repeat the process: 3791 / 640

Going ahead to step 7:
640 goes into 3791 5 times with a remainder of 591.
The number 5 becomes the next digit in our result. 
Result so far: 8885.0
If we take 3200 away from 3791, we end up with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Advancing to step 8:
If we divide 5910 by 640, we get 9 and a remainder of 150.
Record the quotient 9 as the next digit in the result. 
Result so far: 8885.9
Deduct 5760 from 5910 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 9:
640 can be fit into 1500 2 times, resulting in a remainder of 220.
Use 2 as the next digit of our solution. 
Result so far: 8885.92
If we take 1280 away from 1500, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
If we divide 2200 by 640, we get 3 and a remainder of 280.
Record the quotient 3 as the next digit in the result. 
Result so far: 8885.923
If we subtract 1920 from 2200, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
640 goes into 2800 4 times with a remainder of 240.
The number 4 becomes the next digit in our result. 
Result so far: 8885.9234
Subtracting 2560 from 2800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 12:
The number 640 fits into 2400 3 times, leaving a remainder of 480.
Use 3 as the next digit of our solution. 
Result so far: 8885.92343
Subtracting 1920 from 2400 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 13:
640 goes into 4800 7 times with a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 8885.923437
Deduct 4480 from 4800 and we're left 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.

Step 14:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8885.9234375
If we subtract 3200 from 3200, 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.

Advancing to step 15:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8885.9234375
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 8885.9234375 with a balance of 0.0.
