We're dividing 343258 by 64 
We're looking to find how many times 64 goes into 343258.

On to step 1:
3 divided by 64 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 64

Let's proceed to step 2:
When dividing 34 by 64, we get 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 64

Going ahead to step 3:
64 goes into 343 5 times with a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 320 away from 343, we end up with 23.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 64

Advancing to step 4:
64 can be fit into 232 3 times, resulting in a remainder of 40.
The next digit of our result is 3. 
Result so far: 53.0
Deduct 192 from 232 and we're left with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 64

Going ahead to step 5:
If we divide 405 by 64, we get 6 and a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 536.0
The remainder is 21 after subtracting 384 from 405.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 64

Advancing to step 6:
When dividing 218 by 64, we get 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 5363.0
If we subtract 192 from 218, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
When dividing 260 by 64, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 5363.4
The remainder is 4 after subtracting 256 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
64 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 5363.4
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
64 goes into 400 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 5363.406
If we subtract 384 from 400, we 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.

Advancing to step 10:
When dividing 160 by 64, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 5363.4062
Subtracting 128 from 160 leaves us 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.

Let's proceed to step 11:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5363.40625
If we take 320 away from 320, we end up 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.

On 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: 5363.40625
Subtracting 0 from 0 leaves us 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.

Going ahead to step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5363.40625
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 5363.40625, and the remainder is 0.0.
