45646531 divided by 200 
We're looking to find how many times 200 goes into 45646531.

On to step 1:
200 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 200

Advancing to step 2:
If we divide 45 by 200, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 200

Step 3:
When dividing 456 by 200, we get 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 56 after subtracting 400 from 456.
Append the next digit (4) from the dividend to 56 and continue with: 564 / 200

Advancing to step 4:
The number 200 fits into 564 2 times, leaving a remainder of 164.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 400 from 564 leaves us with 164.
Grab the next digit (6) from the dividend, add it to 164, then carry on: 1646 / 200

Moving on to step 5:
The number 200 fits into 1646 8 times, leaving a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 228.0
The remainder is 46 after subtracting 1600 from 1646.
Include the next digit (5) from the dividend after 46, then repeat: 465 / 200

Advancing to step 6:
If we divide 465 by 200, we get 2 and a remainder of 65.
The number 2 becomes the next digit in our result. 
Result so far: 2282.0
Subtracting 400 from 465 leaves us with 65.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 200

On to step 7:
When dividing 653 by 200, we get 3 with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 22823.0
Subtracting 600 from 653 leaves us with 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 200

Let's proceed to step 8:
531 divided by 200 is 2 with a remainder of 131.
Record the quotient 2 as the next digit in the result. 
Result so far: 228232.0
The remainder is 131 after subtracting 400 from 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 9:
200 goes into 1310 6 times with a remainder of 110.
Write down 6 as next digit of the result. 
Result so far: 228232.6
Subtracting 1200 from 1310 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
200 can be fit into 1100 5 times, resulting in a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 228232.65
If we subtract 1000 from 1100, we get 100.
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 11:
200 goes into 1000 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 228232.655
Deduct 1000 from 1000 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.

The final result is 228232.655 with a remainder of 0.0.
