We divide 12686833 by 400
We want to figure out the number of times 12686833 can be divided by 400.

On to step 1:
When dividing 1 by 400, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 400

Let's proceed to step 2:
If we divide 12 by 400, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 400

Advancing to step 3:
126 divided by 400 is 0 with a remainder of 126.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 126 and we're left with 126.
Include the next digit (8) from the dividend after 126, then repeat: 1268 / 400

Moving on to step 4:
400 goes into 1268 3 times with a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 68 after subtracting 1200 from 1268.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 400

Let's proceed to step 5:
If we divide 686 by 400, we get 1 and a remainder of 286.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we take 400 away from 686, we end up with 286.
Bring next digit (8) of the dividend behind the 286 and repeat the process: 2868 / 400

Moving on to step 6:
400 goes into 2868 7 times with a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 317.0
Subtracting 2800 from 2868 leaves us with 68.
Take the next digit (3) from the dividend and append it to 68, then repeat: 683 / 400

Step 7:
The number 400 fits into 683 1 times, leaving a remainder of 283.
Record the quotient 1 as the next digit in the result. 
Result so far: 3171.0
The remainder is 283 after subtracting 400 from 683.
Include the next digit (3) from the dividend after 283, then repeat: 2833 / 400

Moving on to step 8:
When dividing 2833 by 400, we get 7 with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 31717.0
Deduct 2800 from 2833 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
The number 400 fits into 330 0 times, leaving a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 31717.0
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 10:
400 goes into 3300 8 times with a remainder of 100.
The number 8 becomes the next digit in our result. 
Result so far: 31717.08
Deduct 3200 from 3300 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
The number 400 fits into 1000 2 times, leaving a remainder of 200.
Use 2 as the next digit of our solution. 
Result so far: 31717.082
Deduct 800 from 1000 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
400 goes into 2000 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 31717.0825
The remainder is 0 after subtracting 2000 from 2000.
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 13:
400 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31717.0825
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.

Step 14:
The number 400 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 31717.0825
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.

After the division, we end up with 31717.0825 and a remainder of 0.0.
