71157609 ÷ 790 
The aim is to understand the frequency of 790 in 71157609.

Step 1:
790 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 790

On to step 2:
790 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Fetch the next digit (1) from the dividend, attach it to 71 and continue: 711 / 790

Let's proceed to step 3:
When dividing 711 by 790, we get 0 with a remainder of 711.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 711 to get 711.
Append the next digit (5) from the dividend to 711 and continue with: 7115 / 790

Advancing to step 4:
When dividing 7115 by 790, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 7110 from 7115 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 790

Advancing to step 5:
The number 790 fits into 57 0 times, leaving a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
If we take 0 away from 57, we end up with 57.
Include the next digit (6) from the dividend after 57, then repeat: 576 / 790

Let's proceed to step 6:
When dividing 576 by 790, we get 0 with a remainder of 576.
Use 0 as the next digit of our solution. 
Result so far: 900.0
The remainder is 576 after subtracting 0 from 576.
Include the next digit (0) from the dividend after 576, then repeat: 5760 / 790

On to step 7:
If we divide 5760 by 790, we get 7 and a remainder of 230.
The next digit of our result is 7. 
Result so far: 9007.0
The remainder is 230 after subtracting 5530 from 5760.
Append the next digit (9) from the dividend to 230 and continue with: 2309 / 790

Step 8:
When dividing 2309 by 790, we get 2 with a remainder of 729.
Use 2 as the next digit of our solution. 
Result so far: 90072.0
Subtract 1580 from 2309 to get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Advancing to step 9:
790 goes into 7290 9 times with a remainder of 180.
The number 9 becomes the next digit in our result. 
Result so far: 90072.9
If we subtract 7110 from 7290, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
When dividing 1800 by 790, we get 2 with a remainder of 220.
Put 2 as the next digit of the answer. 
Result so far: 90072.92
Subtract 1580 from 1800 to 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.

Let's proceed to step 11:
If we divide 2200 by 790, we get 2 and a remainder of 620.
Use 2 as the next digit of our solution. 
Result so far: 90072.922
Subtract 1580 from 2200 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

The final result is 90072.922 with a remainder of 0.062.
