We're dividing 64400193 by 187 
Our goal is to divide 64400193 by 187.

On to step 1:
If we divide 6 by 187, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 187

Going ahead to step 2:
64 divided by 187 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 187

Moving on to step 3:
When dividing 644 by 187, we get 3 with a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 561 away from 644, we end up with 83.
Include the next digit (0) from the dividend after 83, then repeat: 830 / 187

Moving on to step 4:
187 goes into 830 4 times with a remainder of 82.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 748 from 830, we get 82.
Append the next digit (0) from the dividend to 82 and continue with: 820 / 187

On to step 5:
820 divided by 187 is 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 344.0
Subtract 748 from 820 to get 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 187

Advancing to step 6:
If we divide 721 by 187, we get 3 and a remainder of 160.
Record the quotient 3 as the next digit in the result. 
Result so far: 3443.0
The remainder is 160 after subtracting 561 from 721.
Fetch the next digit (9) from the dividend, attach it to 160 and continue: 1609 / 187

Moving on to step 7:
When dividing 1609 by 187, we get 8 with a remainder of 113.
The next digit of our result is 8. 
Result so far: 34438.0
The remainder is 113 after subtracting 1496 from 1609.
Bring next digit (3) of the dividend behind the 113 and repeat the process: 1133 / 187

Moving on to step 8:
If we divide 1133 by 187, we get 6 and a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 344386.0
Subtracting 1122 from 1133 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
When dividing 110 by 187, we get 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 344386.0
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
When dividing 1100 by 187, we get 5 with a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 344386.05
If we subtract 935 from 1100, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 11:
1650 divided by 187 is 8 with a remainder of 154.
The next digit of our result is 8. 
Result so far: 344386.058
If we take 1496 away from 1650, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 12:
187 can be fit into 1540 8 times, resulting in a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 344386.0588
If we take 1496 away from 1540, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 344386.0588 and a remainder of 0.00044.
