We're dividing 45140609 by 400 
We want to divide 45140609 by 400.

Advancing to step 1:
400 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 400

On to step 2:
400 can be fit into 45 0 times, resulting in a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 400

Step 3:
When dividing 451 by 400, we get 1 with a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 400 from 451, we get 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 400

Moving on to step 4:
400 goes into 514 1 times with a remainder of 114.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 400 from 514, we get 114.
Take the next digit (0) from the dividend and append it to 114, then repeat: 1140 / 400

Step 5:
1140 divided by 400 is 2 with a remainder of 340.
Put 2 as the next digit of the answer. 
Result so far: 112.0
The remainder is 340 after subtracting 800 from 1140.
Take the next digit (6) from the dividend and append it to 340, then repeat: 3406 / 400

On to step 6:
3406 divided by 400 is 8 with a remainder of 206.
Record the quotient 8 as the next digit in the result. 
Result so far: 1128.0
Deduct 3200 from 3406 and we're left with 206.
Include the next digit (0) from the dividend after 206, then repeat: 2060 / 400

Let's proceed to step 7:
2060 divided by 400 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 11285.0
If we subtract 2000 from 2060, we get 60.
Grab the next digit (9) from the dividend, add it to 60, then carry on: 609 / 400

Let's proceed to step 8:
The number 400 fits into 609 1 times, leaving a remainder of 209.
Write down 1 as next digit of the result. 
Result so far: 112851.0
Subtract 400 from 609 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 9:
If we divide 2090 by 400, we get 5 and a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 112851.5
Subtracting 2000 from 2090 leaves us 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.

Let's proceed to step 10:
If we divide 900 by 400, we get 2 and a remainder of 100.
The number 2 becomes the next digit in our result. 
Result so far: 112851.52
Deduct 800 from 900 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.

Moving on to step 11:
400 can be fit into 1000 2 times, resulting in a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 112851.522
The remainder is 200 after subtracting 800 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 112851.522 with a remaining 0.02.
