998642 ÷ 64 
We're looking to find how many times 64 goes into 998642.

Advancing to step 1:
The number 64 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 64

Going ahead to step 2:
The number 64 fits into 99 1 times, leaving a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 35 after subtracting 64 from 99.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 64

Step 3:
64 can be fit into 358 5 times, resulting in a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 320 away from 358, we end up with 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 64

Moving on to step 4:
386 divided by 64 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
Subtracting 384 from 386 leaves us with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 64

On to step 5:
If we divide 24 by 64, we get 0 and a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 1560.0
Subtract 0 from 24 to get 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 64

Advancing to step 6:
242 divided by 64 is 3 with a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 15603.0
If we take 192 away from 242, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
When dividing 500 by 64, we get 7 with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 15603.7
Subtracting 448 from 500 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
64 goes into 520 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 15603.78
If we subtract 512 from 520, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
64 goes into 80 1 times with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 15603.781
Subtract 64 from 80 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
If we divide 160 by 64, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 15603.7812
Deduct 128 from 160 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
64 goes into 320 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15603.78125
The remainder is 0 after subtracting 320 from 320.
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 12:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15603.78125
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.

Let's proceed 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: 15603.78125
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.

After the division, we end up with 15603.78125 and a remainder of 0.0.
