217671 ÷ 64 
The aim is to understand the frequency of 64 in 217671.

Let's proceed to step 1:
64 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 64

Moving on to step 2:
When dividing 21 by 64, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 64

Step 3:
217 divided by 64 is 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 192 from 217 leaves us with 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 64

Advancing to step 4:
When dividing 256 by 64, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we take 256 away from 256, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 64

Advancing to step 5:
64 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 340.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 64

On to step 6:
When dividing 71 by 64, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 3401.0
If we take 64 away from 71, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 64, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 3401.1
Subtract 64 from 70 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
The number 64 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 3401.1
If we subtract 0 from 60, we 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.

Step 9:
64 can be fit into 600 9 times, resulting in a remainder of 24.
The next digit of our result is 9. 
Result so far: 3401.109
If we subtract 576 from 600, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
When dividing 240 by 64, we get 3 with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 3401.1093
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.

Advancing to step 11:
If we divide 480 by 64, we get 7 and a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 3401.10937
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.

Going ahead to step 12:
320 divided by 64 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3401.109375
Deduct 320 from 320 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.

Advancing to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3401.109375
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.

Advancing to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3401.109375
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.

Our division results in 3401.109375 with a remaining 0.0.
