Let's divide 7507908 by 400
Our goal is to divide 7507908 by 400.

Advancing to step 1:
400 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 400

Let's proceed to step 2:
If we divide 75 by 400, we get 0 and a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Bring next digit (0) of the dividend behind the 75 and repeat the process: 750 / 400

Let's proceed to step 3:
When dividing 750 by 400, we get 1 with a remainder of 350.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 400 from 750, we get 350.
Include the next digit (7) from the dividend after 350, then repeat: 3507 / 400

Let's proceed to step 4:
If we divide 3507 by 400, we get 8 and a remainder of 307.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 3200 from 3507 leaves us with 307.
Fetch the next digit (9) from the dividend, attach it to 307 and continue: 3079 / 400

On to step 5:
If we divide 3079 by 400, we get 7 and a remainder of 279.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
Deduct 2800 from 3079 and we're left with 279.
Grab the next digit (0) from the dividend, add it to 279, then carry on: 2790 / 400

On to step 6:
400 can be fit into 2790 6 times, resulting in a remainder of 390.
The next digit of our result is 6. 
Result so far: 1876.0
Subtracting 2400 from 2790 leaves us with 390.
Take the next digit (8) from the dividend and append it to 390, then repeat: 3908 / 400

On to step 7:
400 goes into 3908 9 times with a remainder of 308.
Write down 9 as next digit of the result. 
Result so far: 18769.0
If we subtract 3600 from 3908, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 8:
When dividing 3080 by 400, we get 7 with a remainder of 280.
The number 7 becomes the next digit in our result. 
Result so far: 18769.7
Deduct 2800 from 3080 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 9:
The number 400 fits into 2800 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 18769.77
Subtracting 2800 from 2800 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.

The final result is 18769.77 with a remainder of 0.0.
