We're dividing 71660059 by 790 
The aim is to understand the frequency of 790 in 71660059.

Advancing to step 1:
7 divided by 790 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 790

On to step 2:
If we divide 71 by 790, we get 0 and a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 790

Step 3:
790 goes into 716 0 times with a remainder of 716.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 716, we get 716.
Append the next digit (6) from the dividend to 716 and continue with: 7166 / 790

Going ahead to step 4:
790 goes into 7166 9 times with a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 7110 from 7166, we get 56.
Grab the next digit (0) from the dividend, add it to 56, then carry on: 560 / 790

On to step 5:
790 goes into 560 0 times with a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 90.0
If we subtract 0 from 560, we get 560.
Take the next digit (0) from the dividend and append it to 560, then repeat: 5600 / 790

Let's proceed to step 6:
790 goes into 5600 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 907.0
Subtracting 5530 from 5600 leaves us with 70.
Take the next digit (5) from the dividend and append it to 70, then repeat: 705 / 790

Let's proceed to step 7:
The number 790 fits into 705 0 times, leaving a remainder of 705.
The number 0 becomes the next digit in our result. 
Result so far: 9070.0
Subtract 0 from 705 to get 705.
Take the next digit (9) from the dividend and append it to 705, then repeat: 7059 / 790

Going ahead to step 8:
If we divide 7059 by 790, we get 8 and a remainder of 739.
Use 8 as the next digit of our solution. 
Result so far: 90708.0
If we take 6320 away from 7059, we end up with 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Going ahead to step 9:
7390 divided by 790 is 9 with a remainder of 280.
Write down 9 as next digit of the result. 
Result so far: 90708.9
If we take 7110 away from 7390, we end up 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.

Step 10:
If we divide 2800 by 790, we get 3 and a remainder of 430.
Record the quotient 3 as the next digit in the result. 
Result so far: 90708.93
Deduct 2370 from 2800 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 11:
The number 790 fits into 4300 5 times, leaving a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 90708.935
Subtracting 3950 from 4300 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 12:
When dividing 3500 by 790, we get 4 with a remainder of 340.
Record the quotient 4 as the next digit in the result. 
Result so far: 90708.9354
Deduct 3160 from 3500 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 13:
If we divide 3400 by 790, we get 4 and a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 90708.93544
Subtract 3160 from 3400 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final outcome is 90708.93544, with a leftover of 0.00024.
