Let's divide 28159461 by 400
Our goal is to divide 28159461 by 400.

Going ahead to step 1:
400 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 400

Let's proceed to step 2:
When dividing 28 by 400, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 400

On to step 3:
400 goes into 281 0 times with a remainder of 281.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 281 to get 281.
Bring next digit (5) of the dividend behind the 281 and repeat the process: 2815 / 400

Step 4:
400 goes into 2815 7 times with a remainder of 15.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 2800 from 2815 and we're left with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 400

Going ahead to step 5:
The number 400 fits into 159 0 times, leaving a remainder of 159.
The next digit of our result is 0. 
Result so far: 70.0
Deduct 0 from 159 and we're left with 159.
Take the next digit (4) from the dividend and append it to 159, then repeat: 1594 / 400

Let's proceed to step 6:
400 goes into 1594 3 times with a remainder of 394.
The number 3 becomes the next digit in our result. 
Result so far: 703.0
The remainder is 394 after subtracting 1200 from 1594.
Append the next digit (6) from the dividend to 394 and continue with: 3946 / 400

Let's proceed to step 7:
When dividing 3946 by 400, we get 9 with a remainder of 346.
Record the quotient 9 as the next digit in the result. 
Result so far: 7039.0
If we take 3600 away from 3946, we end up with 346.
Bring next digit (1) of the dividend behind the 346 and repeat the process: 3461 / 400

Going ahead to step 8:
The number 400 fits into 3461 8 times, leaving a remainder of 261.
Put 8 as the next digit of the answer. 
Result so far: 70398.0
Deduct 3200 from 3461 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 9:
400 goes into 2610 6 times with a remainder of 210.
Write down 6 as next digit of the result. 
Result so far: 70398.6
Subtracting 2400 from 2610 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
The number 400 fits into 2100 5 times, leaving a remainder of 100.
The next digit of our result is 5. 
Result so far: 70398.65
Subtract 2000 from 2100 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.

Moving on to step 11:
1000 divided by 400 is 2 with a remainder of 200.
Use 2 as the next digit of our solution. 
Result so far: 70398.652
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.

Moving on to step 12:
400 can be fit into 2000 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 70398.6525
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.

Let's proceed to step 13:
400 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 70398.6525
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.

Moving on to step 14:
400 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 70398.6525
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.

After the division, we end up with 70398.6525 and a remainder of 0.0.
