1387492 ÷ 217 
The aim is to understand the frequency of 217 in 1387492.

Advancing to step 1:
217 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 217

Advancing to step 2:
13 divided by 217 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 217

Going ahead to step 3:
217 goes into 138 0 times with a remainder of 138.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 138, we get 138.
Take the next digit (7) from the dividend and append it to 138, then repeat: 1387 / 217

Let's proceed to step 4:
When dividing 1387 by 217, we get 6 with a remainder of 85.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 85 after subtracting 1302 from 1387.
Fetch the next digit (4) from the dividend, attach it to 85 and continue: 854 / 217

Advancing to step 5:
The number 217 fits into 854 3 times, leaving a remainder of 203.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
The remainder is 203 after subtracting 651 from 854.
Take the next digit (9) from the dividend and append it to 203, then repeat: 2039 / 217

Advancing to step 6:
When dividing 2039 by 217, we get 9 with a remainder of 86.
The next digit of our result is 9. 
Result so far: 639.0
Deduct 1953 from 2039 and we're left with 86.
Append the next digit (2) from the dividend to 86 and continue with: 862 / 217

Going ahead to step 7:
217 goes into 862 3 times with a remainder of 211.
Record the quotient 3 as the next digit in the result. 
Result so far: 6393.0
Subtracting 651 from 862 leaves us with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 8:
2110 divided by 217 is 9 with a remainder of 157.
Record the quotient 9 as the next digit in the result. 
Result so far: 6393.9
Subtract 1953 from 2110 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 9:
217 goes into 1570 7 times with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 6393.97
Subtracting 1519 from 1570 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 10:
If we divide 510 by 217, we get 2 and a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 6393.972
The remainder is 76 after subtracting 434 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 11:
When dividing 760 by 217, we get 3 with a remainder of 109.
The next digit of our result is 3. 
Result so far: 6393.9723
The remainder is 109 after subtracting 651 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 12:
1090 divided by 217 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 6393.97235
Subtracting 1085 from 1090 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
217 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 6393.97235
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
When dividing 500 by 217, we get 2 with a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 6393.9723502
If we take 434 away from 500, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 15:
660 divided by 217 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 6393.97235023
If we take 651 away from 660, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 6393.97235023 with a remaining 9e-09.
