10125146 divided by 200 
We're looking to find how many times 200 goes into 10125146.

Step 1:
1 divided by 200 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 200

On to step 2:
When dividing 10 by 200, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 200

Advancing to step 3:
If we divide 101 by 200, we get 0 and a remainder of 101.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 101, we end up with 101.
Bring next digit (2) of the dividend behind the 101 and repeat the process: 1012 / 200

Let's proceed to step 4:
1012 divided by 200 is 5 with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 1000 from 1012 to get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 200

Going ahead to step 5:
The number 200 fits into 125 0 times, leaving a remainder of 125.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 125 to get 125.
Take the next digit (1) from the dividend and append it to 125, then repeat: 1251 / 200

Step 6:
When dividing 1251 by 200, we get 6 with a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 506.0
The remainder is 51 after subtracting 1200 from 1251.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 200

On to step 7:
If we divide 514 by 200, we get 2 and a remainder of 114.
The number 2 becomes the next digit in our result. 
Result so far: 5062.0
If we take 400 away from 514, we end up with 114.
Include the next digit (6) from the dividend after 114, then repeat: 1146 / 200

Going ahead to step 8:
200 can be fit into 1146 5 times, resulting in a remainder of 146.
Use 5 as the next digit of our solution. 
Result so far: 50625.0
Subtract 1000 from 1146 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 9:
When dividing 1460 by 200, we get 7 with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 50625.7
If we take 1400 away from 1460, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
If we divide 600 by 200, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 50625.73
Subtract 600 from 600 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.

On to step 11:
200 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 50625.73
The remainder is 0 after subtracting 0 from 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 12:
If we divide 0 by 200, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50625.73
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.

The final result is 50625.73 with a remainder of 0.0.
