We're dividing 31828466 by 640 
We want to divide 31828466 by 640.

Moving on to step 1:
640 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 640

Step 2:
The number 640 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 640

Step 3:
When dividing 318 by 640, we get 0 with a remainder of 318.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 318, we get 318.
Take the next digit (2) from the dividend and append it to 318, then repeat: 3182 / 640

Moving on to step 4:
640 goes into 3182 4 times with a remainder of 622.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2560 away from 3182, we end up with 622.
Take the next digit (8) from the dividend and append it to 622, then repeat: 6228 / 640

Advancing to step 5:
640 can be fit into 6228 9 times, resulting in a remainder of 468.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 5760 from 6228, we get 468.
Grab the next digit (4) from the dividend, add it to 468, then carry on: 4684 / 640

Going ahead to step 6:
If we divide 4684 by 640, we get 7 and a remainder of 204.
The next digit of our result is 7. 
Result so far: 497.0
If we take 4480 away from 4684, we end up with 204.
Bring next digit (6) of the dividend behind the 204 and repeat the process: 2046 / 640

Going ahead to step 7:
640 can be fit into 2046 3 times, resulting in a remainder of 126.
The next digit of our result is 3. 
Result so far: 4973.0
The remainder is 126 after subtracting 1920 from 2046.
Append the next digit (6) from the dividend to 126 and continue with: 1266 / 640

On to step 8:
1266 divided by 640 is 1 with a remainder of 626.
The next digit of our result is 1. 
Result so far: 49731.0
Deduct 640 from 1266 and we're left with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Going ahead to step 9:
640 goes into 6260 9 times with a remainder of 500.
Put 9 as the next digit of the answer. 
Result so far: 49731.9
Deduct 5760 from 6260 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 10:
If we divide 5000 by 640, we get 7 and a remainder of 520.
The number 7 becomes the next digit in our result. 
Result so far: 49731.97
Subtract 4480 from 5000 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 11:
The number 640 fits into 5200 8 times, leaving a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 49731.978
The remainder is 80 after subtracting 5120 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
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: 49731.9781
Deduct 640 from 800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 13:
640 can be fit into 1600 2 times, resulting in a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 49731.97812
Deduct 1280 from 1600 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.

Let's proceed to 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: 49731.978125
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.

Step 15:
When dividing 0 by 640, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 49731.978125
Subtract 0 from 0 to 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.

Moving on to step 16:
When dividing 0 by 640, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 49731.978125
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.

After the division, we end up with 49731.978125 and a remainder of 0.0.
