We look at the division of 61658209 by 400 
Let's see how many times 400 fits into 61658209.

Let's proceed to step 1:
400 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 400

Going ahead to step 2:
61 divided by 400 is 0 with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 400

On to step 3:
The number 400 fits into 616 1 times, leaving a remainder of 216.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 400 from 616, we get 216.
Grab the next digit (5) from the dividend, add it to 216, then carry on: 2165 / 400

Going ahead to step 4:
400 goes into 2165 5 times with a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 2000 from 2165 leaves us with 165.
Fetch the next digit (8) from the dividend, attach it to 165 and continue: 1658 / 400

On to step 5:
When dividing 1658 by 400, we get 4 with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 154.0
The remainder is 58 after subtracting 1600 from 1658.
Fetch the next digit (2) from the dividend, attach it to 58 and continue: 582 / 400

Advancing to step 6:
The number 400 fits into 582 1 times, leaving a remainder of 182.
Put 1 as the next digit of the answer. 
Result so far: 1541.0
Subtract 400 from 582 to get 182.
Grab the next digit (0) from the dividend, add it to 182, then carry on: 1820 / 400

Let's proceed to step 7:
The number 400 fits into 1820 4 times, leaving a remainder of 220.
Record the quotient 4 as the next digit in the result. 
Result so far: 15414.0
Subtract 1600 from 1820 to get 220.
Include the next digit (9) from the dividend after 220, then repeat: 2209 / 400

Moving on to step 8:
When dividing 2209 by 400, we get 5 with a remainder of 209.
Put 5 as the next digit of the answer. 
Result so far: 154145.0
Subtract 2000 from 2209 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 9:
The number 400 fits into 2090 5 times, leaving a remainder of 90.
The next digit of our result is 5. 
Result so far: 154145.5
If we subtract 2000 from 2090, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
900 divided by 400 is 2 with a remainder of 100.
Use 2 as the next digit of our solution. 
Result so far: 154145.52
If we subtract 800 from 900, we 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.

Going ahead to step 11:
When dividing 1000 by 400, we get 2 with a remainder of 200.
Write down 2 as next digit of the result. 
Result so far: 154145.522
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 154145.522 with a remainder of 0.02.
