We divide 45116929 by 400
We want to figure out the number of times 45116929 can be divided by 400.

Advancing to step 1:
When dividing 4 by 400, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 400

On to step 2:
45 divided by 400 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 400

Step 3:
400 goes into 451 1 times with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 400 from 451 to get 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 400

Let's proceed to step 4:
When dividing 511 by 400, we get 1 with a remainder of 111.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 400 from 511 and we're left with 111.
Fetch the next digit (6) from the dividend, attach it to 111 and continue: 1116 / 400

On to step 5:
400 can be fit into 1116 2 times, resulting in a remainder of 316.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
Deduct 800 from 1116 and we're left with 316.
Append the next digit (9) from the dividend to 316 and continue with: 3169 / 400

Let's proceed to step 6:
When dividing 3169 by 400, we get 7 with a remainder of 369.
The number 7 becomes the next digit in our result. 
Result so far: 1127.0
Subtracting 2800 from 3169 leaves us with 369.
Grab the next digit (2) from the dividend, add it to 369, then carry on: 3692 / 400

Let's proceed to step 7:
3692 divided by 400 is 9 with a remainder of 92.
Use 9 as the next digit of our solution. 
Result so far: 11279.0
The remainder is 92 after subtracting 3600 from 3692.
Append the next digit (9) from the dividend to 92 and continue with: 929 / 400

Moving on to step 8:
400 can be fit into 929 2 times, resulting in a remainder of 129.
Use 2 as the next digit of our solution. 
Result so far: 112792.0
The remainder is 129 after subtracting 800 from 929.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 9:
The number 400 fits into 1290 3 times, leaving a remainder of 90.
The number 3 becomes the next digit in our result. 
Result so far: 112792.3
If we take 1200 away from 1290, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
When dividing 900 by 400, we get 2 with a remainder of 100.
Use 2 as the next digit of our solution. 
Result so far: 112792.32
Subtract 800 from 900 to 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.

Advancing to step 11:
If we divide 1000 by 400, we get 2 and a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 112792.322
If we take 800 away from 1000, 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.

The final result is 112792.322 with a remainder of 0.02.
