10117338 ÷ 400 
We want to figure out the number of times 10117338 can be divided by 400.

Step 1:
The number 400 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 400

Going ahead to step 2:
400 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 400

Moving on to step 3:
400 goes into 101 0 times with a remainder of 101.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 101 after subtracting 0 from 101.
Fetch the next digit (1) from the dividend, attach it to 101 and continue: 1011 / 400

Step 4:
400 can be fit into 1011 2 times, resulting in a remainder of 211.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 800 from 1011 and we're left with 211.
Append the next digit (7) from the dividend to 211 and continue with: 2117 / 400

Moving on to step 5:
When dividing 2117 by 400, we get 5 with a remainder of 117.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 2000 from 2117 and we're left with 117.
Include the next digit (3) from the dividend after 117, then repeat: 1173 / 400

On to step 6:
400 goes into 1173 2 times with a remainder of 373.
Record the quotient 2 as the next digit in the result. 
Result so far: 252.0
Subtract 800 from 1173 to get 373.
Take the next digit (3) from the dividend and append it to 373, then repeat: 3733 / 400

Let's proceed to step 7:
3733 divided by 400 is 9 with a remainder of 133.
Write down 9 as next digit of the result. 
Result so far: 2529.0
The remainder is 133 after subtracting 3600 from 3733.
Take the next digit (8) from the dividend and append it to 133, then repeat: 1338 / 400

Going ahead to step 8:
When dividing 1338 by 400, we get 3 with a remainder of 138.
Use 3 as the next digit of our solution. 
Result so far: 25293.0
Subtract 1200 from 1338 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 9:
The number 400 fits into 1380 3 times, leaving a remainder of 180.
The number 3 becomes the next digit in our result. 
Result so far: 25293.3
Subtracting 1200 from 1380 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 10:
The number 400 fits into 1800 4 times, leaving a remainder of 200.
Write down 4 as next digit of the result. 
Result so far: 25293.34
If we take 1600 away from 1800, we end up 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.

Let's proceed to step 11:
When dividing 2000 by 400, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 25293.345
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.

On to step 12:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25293.345
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 13:
When dividing 0 by 400, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25293.345
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 25293.345, with a leftover of 0.0.
