We look at the division of 198438 by 64 
We're looking to find how many times 64 goes into 198438.

Going ahead to step 1:
The number 64 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 64

Moving on to step 2:
If we divide 19 by 64, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 64

Let's proceed to step 3:
If we divide 198 by 64, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 6 after subtracting 192 from 198.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 64

On to step 4:
64 goes into 64 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 0 after subtracting 64 from 64.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 64

Going ahead to step 5:
When dividing 3 by 64, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 310.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 64

Advancing to step 6:
38 divided by 64 is 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 3100.0
Subtracting 0 from 38 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
The number 64 fits into 380 5 times, leaving a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 3100.5
Subtract 320 from 380 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
600 divided by 64 is 9 with a remainder of 24.
The next digit of our result is 9. 
Result so far: 3100.59
The remainder is 24 after subtracting 576 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
If we divide 240 by 64, we get 3 and a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 3100.593
The remainder is 48 after subtracting 192 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
64 can be fit into 480 7 times, resulting in a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 3100.5937
If we subtract 448 from 480, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
64 goes into 320 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3100.59375
If we subtract 320 from 320, we 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 12:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3100.59375
If we subtract 0 from 0, we 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.

Going ahead to step 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3100.59375
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 3100.59375, and the remainder is 0.0.
