We look at the division of 90493905 by 709 
The aim is to understand the frequency of 709 in 90493905.

Let's proceed to step 1:
709 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 709

Let's proceed to step 2:
When dividing 90 by 709, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Fetch the next digit (4) from the dividend, attach it to 90 and continue: 904 / 709

Going ahead to step 3:
709 goes into 904 1 times with a remainder of 195.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 195 after subtracting 709 from 904.
Append the next digit (9) from the dividend to 195 and continue with: 1959 / 709

On to step 4:
The number 709 fits into 1959 2 times, leaving a remainder of 541.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 541 after subtracting 1418 from 1959.
Grab the next digit (3) from the dividend, add it to 541, then carry on: 5413 / 709

Advancing to step 5:
The number 709 fits into 5413 7 times, leaving a remainder of 450.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
If we subtract 4963 from 5413, we get 450.
Include the next digit (9) from the dividend after 450, then repeat: 4509 / 709

Advancing to step 6:
4509 divided by 709 is 6 with a remainder of 255.
Use 6 as the next digit of our solution. 
Result so far: 1276.0
Subtract 4254 from 4509 to get 255.
Fetch the next digit (0) from the dividend, attach it to 255 and continue: 2550 / 709

Going ahead to step 7:
When dividing 2550 by 709, we get 3 with a remainder of 423.
Record the quotient 3 as the next digit in the result. 
Result so far: 12763.0
The remainder is 423 after subtracting 2127 from 2550.
Grab the next digit (5) from the dividend, add it to 423, then carry on: 4235 / 709

On to step 8:
709 can be fit into 4235 5 times, resulting in a remainder of 690.
The number 5 becomes the next digit in our result. 
Result so far: 127635.0
The remainder is 690 after subtracting 3545 from 4235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Moving on to step 9:
If we divide 6900 by 709, we get 9 and a remainder of 519.
Write down 9 as next digit of the result. 
Result so far: 127635.9
Subtract 6381 from 6900 to get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Step 10:
709 can be fit into 5190 7 times, resulting in a remainder of 227.
Write down 7 as next digit of the result. 
Result so far: 127635.97
Subtracting 4963 from 5190 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 11:
709 goes into 2270 3 times with a remainder of 143.
Use 3 as the next digit of our solution. 
Result so far: 127635.973
If we take 2127 away from 2270, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 12:
The number 709 fits into 1430 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 127635.9732
Subtracting 1418 from 1430 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
120 divided by 709 is 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 127635.9732
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 14:
The number 709 fits into 1200 1 times, leaving a remainder of 491.
The next digit of our result is 1. 
Result so far: 127635.973201
Subtract 709 from 1200 to get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Let's proceed to step 15:
709 can be fit into 4910 6 times, resulting in a remainder of 656.
Write down 6 as next digit of the result. 
Result so far: 127635.9732016
The remainder is 656 after subtracting 4254 from 4910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 16:
6560 divided by 709 is 9 with a remainder of 179.
The next digit of our result is 9. 
Result so far: 127635.97320169
If we take 6381 away from 6560, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

In conclusion, the division gives 127635.97320169 with a balance of 1.79e-07.
