We're dividing 73285236 by 640 
We want to divide 73285236 by 640.

Step 1:
If we divide 7 by 640, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 640

Going ahead to step 2:
If we divide 73 by 640, we get 0 and a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Grab the next digit (2) from the dividend, add it to 73, then carry on: 732 / 640

Let's proceed to step 3:
When dividing 732 by 640, we get 1 with a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 92 after subtracting 640 from 732.
Grab the next digit (8) from the dividend, add it to 92, then carry on: 928 / 640

Advancing to step 4:
When dividing 928 by 640, we get 1 with a remainder of 288.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 640 from 928 and we're left with 288.
Include the next digit (5) from the dividend after 288, then repeat: 2885 / 640

Going ahead to step 5:
2885 divided by 640 is 4 with a remainder of 325.
Put 4 as the next digit of the answer. 
Result so far: 114.0
The remainder is 325 after subtracting 2560 from 2885.
Bring next digit (2) of the dividend behind the 325 and repeat the process: 3252 / 640

Moving on to step 6:
When dividing 3252 by 640, we get 5 with a remainder of 52.
The next digit of our result is 5. 
Result so far: 1145.0
If we subtract 3200 from 3252, we get 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 640

On to step 7:
If we divide 523 by 640, we get 0 and a remainder of 523.
The next digit of our result is 0. 
Result so far: 11450.0
If we take 0 away from 523, we end up with 523.
Take the next digit (6) from the dividend and append it to 523, then repeat: 5236 / 640

Let's proceed to step 8:
640 goes into 5236 8 times with a remainder of 116.
The number 8 becomes the next digit in our result. 
Result so far: 114508.0
Deduct 5120 from 5236 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 9:
640 goes into 1160 1 times with a remainder of 520.
Record the quotient 1 as the next digit in the result. 
Result so far: 114508.1
If we take 640 away from 1160, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 10:
5200 divided by 640 is 8 with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 114508.18
Subtracting 5120 from 5200 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
640 can be fit into 800 1 times, resulting in a remainder of 160.
Write down 1 as next digit of the result. 
Result so far: 114508.181
If we subtract 640 from 800, 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.

Let's proceed to step 12:
640 goes into 1600 2 times with a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 114508.1812
Subtracting 1280 from 1600 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.

Step 13:
640 goes into 3200 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 114508.18125
Subtracting 3200 from 3200 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.

Going ahead to step 14:
When dividing 0 by 640, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 114508.18125
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.

Moving on to step 15:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 114508.18125
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.

After the division, we end up with 114508.18125 and a remainder of 0.0.
