309953 ÷ 64 
Our goal is to divide 309953 by 64.

On to step 1:
If we divide 3 by 64, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 64

Step 2:
64 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 64

Let's proceed to step 3:
The number 64 fits into 309 4 times, leaving a remainder of 53.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 256 away from 309, we end up with 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 64

Going ahead to step 4:
The number 64 fits into 539 8 times, leaving a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 512 away from 539, we end up with 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 64

Advancing to step 5:
64 goes into 275 4 times with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 484.0
Subtracting 256 from 275 leaves us with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 64

On to step 6:
When dividing 193 by 64, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 4843.0
Subtracting 192 from 193 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
When dividing 10 by 64, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4843.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 64 is 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 4843.01
Deduct 64 from 100 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
If we divide 360 by 64, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 4843.015
Deduct 320 from 360 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
64 goes into 400 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 4843.0156
Deduct 384 from 400 and we're left with 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 11:
The number 64 fits into 160 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 4843.01562
If we subtract 128 from 160, 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.

Let's proceed to step 12:
320 divided by 64 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4843.015625
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.

Going ahead to step 13:
0 divided by 64 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4843.015625
If we take 0 away from 0, 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 14:
64 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4843.015625
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 4843.015625, and the remainder is 0.0.
