Let's divide 551821 by 64
We want to figure out the number of times 551821 can be divided by 64.

Going ahead to step 1:
64 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 64

Going ahead to step 2:
The number 64 fits into 55 0 times, leaving a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Bring next digit (1) of the dividend behind the 55 and repeat the process: 551 / 64

Moving on to step 3:
When dividing 551 by 64, we get 8 with a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 39 after subtracting 512 from 551.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 64

Let's proceed to step 4:
When dividing 398 by 64, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we take 384 away from 398, we end up with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 64

Advancing to step 5:
When dividing 142 by 64, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 862.0
The remainder is 14 after subtracting 128 from 142.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 64

Going ahead to step 6:
64 can be fit into 141 2 times, resulting in a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 8622.0
Subtract 128 from 141 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
The number 64 fits into 130 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 8622.2
If we subtract 128 from 130, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 64, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8622.2
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
64 goes into 200 3 times with a remainder of 8.
The next digit of our result is 3. 
Result so far: 8622.203
Deduct 192 from 200 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
64 can be fit into 80 1 times, resulting in a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 8622.2031
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.

Advancing to step 11:
When dividing 160 by 64, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 8622.20312
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.

Step 12:
If we divide 320 by 64, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8622.203125
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 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8622.203125
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.

Advancing to step 14:
If we divide 0 by 64, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8622.203125
Subtract 0 from 0 to 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 8622.203125 and a remainder of 0.0.
