We look at the division of 8972870 by 735 
The aim is to understand the frequency of 735 in 8972870.

Let's proceed to step 1:
735 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 735

Moving on to step 2:
735 goes into 89 0 times with a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Take the next digit (7) from the dividend and append it to 89, then repeat: 897 / 735

Going ahead to step 3:
735 can be fit into 897 1 times, resulting in a remainder of 162.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 735 from 897 and we're left with 162.
Include the next digit (2) from the dividend after 162, then repeat: 1622 / 735

Advancing to step 4:
If we divide 1622 by 735, we get 2 and a remainder of 152.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1470 from 1622 to get 152.
Append the next digit (8) from the dividend to 152 and continue with: 1528 / 735

Going ahead to step 5:
The number 735 fits into 1528 2 times, leaving a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 122.0
If we take 1470 away from 1528, we end up with 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 735

Advancing to step 6:
735 can be fit into 587 0 times, resulting in a remainder of 587.
Use 0 as the next digit of our solution. 
Result so far: 1220.0
Subtract 0 from 587 to get 587.
Grab the next digit (0) from the dividend, add it to 587, then carry on: 5870 / 735

Going ahead to step 7:
735 can be fit into 5870 7 times, resulting in a remainder of 725.
Record the quotient 7 as the next digit in the result. 
Result so far: 12207.0
Subtracting 5145 from 5870 leaves us with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Advancing to step 8:
When dividing 7250 by 735, we get 9 with a remainder of 635.
Put 9 as the next digit of the answer. 
Result so far: 12207.9
Deduct 6615 from 7250 and we're left with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Going ahead to step 9:
If we divide 6350 by 735, we get 8 and a remainder of 470.
The next digit of our result is 8. 
Result so far: 12207.98
If we take 5880 away from 6350, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 10:
735 can be fit into 4700 6 times, resulting in a remainder of 290.
The next digit of our result is 6. 
Result so far: 12207.986
If we subtract 4410 from 4700, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 11:
If we divide 2900 by 735, we get 3 and a remainder of 695.
Use 3 as the next digit of our solution. 
Result so far: 12207.9863
If we subtract 2205 from 2900, we get 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Let's proceed to step 12:
6950 divided by 735 is 9 with a remainder of 335.
Record the quotient 9 as the next digit in the result. 
Result so far: 12207.98639
If we subtract 6615 from 6950, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 13:
The number 735 fits into 3350 4 times, leaving a remainder of 410.
The number 4 becomes the next digit in our result. 
Result so far: 12207.986394
The remainder is 410 after subtracting 2940 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 14:
If we divide 4100 by 735, we get 5 and a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 12207.9863945
If we subtract 3675 from 4100, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 15:
The number 735 fits into 4250 5 times, leaving a remainder of 575.
Write down 5 as next digit of the result. 
Result so far: 12207.98639455
Subtract 3675 from 4250 to get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

In conclusion, the division gives 12207.98639455 with a balance of 5.75e-07.
