We divide 4578700 by 400
We want to figure out the number of times 4578700 can be divided by 400.

On to step 1:
4 divided by 400 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 400

Let's proceed to step 2:
When dividing 45 by 400, we get 0 with 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.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 400

Let's proceed to step 3:
457 divided by 400 is 1 with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 400 from 457, we get 57.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 400

Advancing to step 4:
The number 400 fits into 578 1 times, leaving a remainder of 178.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 400 from 578 leaves us with 178.
Take the next digit (7) from the dividend and append it to 178, then repeat: 1787 / 400

Advancing to step 5:
The number 400 fits into 1787 4 times, leaving a remainder of 187.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Subtracting 1600 from 1787 leaves us with 187.
Take the next digit (0) from the dividend and append it to 187, then repeat: 1870 / 400

Advancing to step 6:
400 can be fit into 1870 4 times, resulting in a remainder of 270.
Use 4 as the next digit of our solution. 
Result so far: 1144.0
If we subtract 1600 from 1870, we get 270.
Take the next digit (0) from the dividend and append it to 270, then repeat: 2700 / 400

Step 7:
When dividing 2700 by 400, we get 6 with a remainder of 300.
Use 6 as the next digit of our solution. 
Result so far: 11446.0
Deduct 2400 from 2700 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 8:
3000 divided by 400 is 7 with a remainder of 200.
Use 7 as the next digit of our solution. 
Result so far: 11446.7
The remainder is 200 after subtracting 2800 from 3000.
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 9:
If we divide 2000 by 400, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 11446.75
Subtracting 2000 from 2000 leaves us 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 10:
0 divided by 400 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11446.75
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.

Let's proceed to step 11:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11446.75
Deduct 0 from 0 and we're left 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.

Our division results in 11446.75 with a remaining 0.0.
