We divide 46512122 by 640
We want to divide 46512122 by 640.

Step 1:
640 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 640

Let's proceed to step 2:
46 divided by 640 is 0 with a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 46 to get 46.
Include the next digit (5) from the dividend after 46, then repeat: 465 / 640

Going ahead to step 3:
640 goes into 465 0 times with a remainder of 465.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 465, we end up with 465.
Append the next digit (1) from the dividend to 465 and continue with: 4651 / 640

Moving on to step 4:
640 can be fit into 4651 7 times, resulting in a remainder of 171.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 4480 from 4651 to get 171.
Take the next digit (2) from the dividend and append it to 171, then repeat: 1712 / 640

Moving on to step 5:
1712 divided by 640 is 2 with a remainder of 432.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 432 after subtracting 1280 from 1712.
Take the next digit (1) from the dividend and append it to 432, then repeat: 4321 / 640

Let's proceed to step 6:
The number 640 fits into 4321 6 times, leaving a remainder of 481.
Put 6 as the next digit of the answer. 
Result so far: 726.0
The remainder is 481 after subtracting 3840 from 4321.
Append the next digit (2) from the dividend to 481 and continue with: 4812 / 640

Moving on to step 7:
640 goes into 4812 7 times with a remainder of 332.
The next digit of our result is 7. 
Result so far: 7267.0
Subtract 4480 from 4812 to get 332.
Fetch the next digit (2) from the dividend, attach it to 332 and continue: 3322 / 640

Step 8:
When dividing 3322 by 640, we get 5 with a remainder of 122.
Put 5 as the next digit of the answer. 
Result so far: 72675.0
The remainder is 122 after subtracting 3200 from 3322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
640 goes into 1220 1 times with a remainder of 580.
Put 1 as the next digit of the answer. 
Result so far: 72675.1
If we take 640 away from 1220, we end up 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.

Step 10:
If we divide 5800 by 640, we get 9 and a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 72675.19
The remainder is 40 after subtracting 5760 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
The number 640 fits into 400 0 times, leaving a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 72675.19
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.

Going ahead to step 12:
When dividing 4000 by 640, we get 6 with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 72675.1906
Subtract 3840 from 4000 to 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 13:
If we divide 1600 by 640, we get 2 and a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 72675.19062
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.

Moving 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: 72675.190625
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.

Let's proceed to 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: 72675.190625
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.

On to step 16:
0 divided by 640 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 72675.190625
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.

The final outcome is 72675.190625, with a leftover of 0.0.
