46628609 ÷ 400 
Let's see how many times 400 fits into 46628609.

Going ahead to step 1:
If we divide 4 by 400, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 400

Step 2:
46 divided by 400 is 0 with a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 46, we end up with 46.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 400

On to step 3:
If we divide 466 by 400, we get 1 and a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 400 from 466 to get 66.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 400

Let's proceed to step 4:
If we divide 662 by 400, we get 1 and a remainder of 262.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 400 away from 662, we end up with 262.
Include the next digit (8) from the dividend after 262, then repeat: 2628 / 400

On to step 5:
If we divide 2628 by 400, we get 6 and a remainder of 228.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Deduct 2400 from 2628 and we're left with 228.
Take the next digit (6) from the dividend and append it to 228, then repeat: 2286 / 400

On to step 6:
2286 divided by 400 is 5 with a remainder of 286.
Write down 5 as next digit of the result. 
Result so far: 1165.0
Subtracting 2000 from 2286 leaves us with 286.
Include the next digit (0) from the dividend after 286, then repeat: 2860 / 400

Advancing to step 7:
400 can be fit into 2860 7 times, resulting in a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 11657.0
Subtracting 2800 from 2860 leaves us with 60.
Grab the next digit (9) from the dividend, add it to 60, then carry on: 609 / 400

Going ahead to step 8:
609 divided by 400 is 1 with a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 116571.0
The remainder is 209 after subtracting 400 from 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 9:
400 can be fit into 2090 5 times, resulting in a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 116571.5
If we take 2000 away from 2090, we end up 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.

Moving on to step 10:
400 goes into 900 2 times with a remainder of 100.
Write down 2 as next digit of the result. 
Result so far: 116571.52
The remainder is 100 after subtracting 800 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
1000 divided by 400 is 2 with a remainder of 200.
The next digit of our result is 2. 
Result so far: 116571.522
If we subtract 800 from 1000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 116571.522 with a remainder of 0.02.
