Let's divide 8158992 by 400
Our goal is to divide 8158992 by 400.

Let's proceed to step 1:
400 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 400

Going ahead to step 2:
81 divided by 400 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 400

Let's proceed to step 3:
815 divided by 400 is 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 800 from 815 leaves us with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 400

Let's proceed to step 4:
400 goes into 158 0 times with a remainder of 158.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 158 to get 158.
Grab the next digit (9) from the dividend, add it to 158, then carry on: 1589 / 400

Going ahead to step 5:
400 goes into 1589 3 times with a remainder of 389.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
If we subtract 1200 from 1589, we get 389.
Grab the next digit (9) from the dividend, add it to 389, then carry on: 3899 / 400

Moving on to step 6:
400 can be fit into 3899 9 times, resulting in a remainder of 299.
The number 9 becomes the next digit in our result. 
Result so far: 2039.0
Subtracting 3600 from 3899 leaves us with 299.
Take the next digit (2) from the dividend and append it to 299, then repeat: 2992 / 400

Moving on to step 7:
The number 400 fits into 2992 7 times, leaving a remainder of 192.
The number 7 becomes the next digit in our result. 
Result so far: 20397.0
The remainder is 192 after subtracting 2800 from 2992.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 8:
400 can be fit into 1920 4 times, resulting in a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 20397.4
The remainder is 320 after subtracting 1600 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 9:
If we divide 3200 by 400, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 20397.48
If we take 3200 away from 3200, 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.

On to step 10:
400 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20397.48
Subtracting 0 from 0 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.

Going ahead to step 11:
When dividing 0 by 400, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20397.48
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.

The quotient of the division is 20397.48, and the remainder is 0.0.
