We look at the division of 71712490 by 705 
The aim is to understand the frequency of 705 in 71712490.

Step 1:
The number 705 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 705

Moving on to step 2:
71 divided by 705 is 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Include the next digit (7) from the dividend after 71, then repeat: 717 / 705

Let's proceed to step 3:
When dividing 717 by 705, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 705 from 717 to get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 705

Let's proceed to step 4:
705 can be fit into 121 0 times, resulting in a remainder of 121.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 121, we end up with 121.
Grab the next digit (2) from the dividend, add it to 121, then carry on: 1212 / 705

Advancing to step 5:
The number 705 fits into 1212 1 times, leaving a remainder of 507.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Deduct 705 from 1212 and we're left with 507.
Append the next digit (4) from the dividend to 507 and continue with: 5074 / 705

Let's proceed to step 6:
705 can be fit into 5074 7 times, resulting in a remainder of 139.
The next digit of our result is 7. 
Result so far: 1017.0
Subtracting 4935 from 5074 leaves us with 139.
Take the next digit (9) from the dividend and append it to 139, then repeat: 1399 / 705

Going ahead to step 7:
705 goes into 1399 1 times with a remainder of 694.
Write down 1 as next digit of the result. 
Result so far: 10171.0
Subtract 705 from 1399 to get 694.
Include the next digit (0) from the dividend after 694, then repeat: 6940 / 705

Let's proceed to step 8:
705 can be fit into 6940 9 times, resulting in a remainder of 595.
Record the quotient 9 as the next digit in the result. 
Result so far: 101719.0
If we subtract 6345 from 6940, we get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 9:
5950 divided by 705 is 8 with a remainder of 310.
Put 8 as the next digit of the answer. 
Result so far: 101719.8
Subtracting 5640 from 5950 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 10:
705 can be fit into 3100 4 times, resulting in a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 101719.84
Subtracting 2820 from 3100 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 11:
If we divide 2800 by 705, we get 3 and a remainder of 685.
The next digit of our result is 3. 
Result so far: 101719.843
Subtract 2115 from 2800 to get 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Advancing to step 12:
705 can be fit into 6850 9 times, resulting in a remainder of 505.
The number 9 becomes the next digit in our result. 
Result so far: 101719.8439
Deduct 6345 from 6850 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Let's proceed to step 13:
705 can be fit into 5050 7 times, resulting in a remainder of 115.
Record the quotient 7 as the next digit in the result. 
Result so far: 101719.84397
If we subtract 4935 from 5050, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 14:
When dividing 1150 by 705, we get 1 with a remainder of 445.
Record the quotient 1 as the next digit in the result. 
Result so far: 101719.843971
The remainder is 445 after subtracting 705 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

On to step 15:
If we divide 4450 by 705, we get 6 and a remainder of 220.
Record the quotient 6 as the next digit in the result. 
Result so far: 101719.8439716
If we subtract 4230 from 4450, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 16:
If we divide 2200 by 705, we get 3 and a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 101719.84397163
Deduct 2115 from 2200 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final result is 101719.84397163 with a remainder of 8.5e-08.
