We're dividing 87619403 by 797 
The aim is to understand the frequency of 797 in 87619403.

Going ahead to step 1:
797 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 797

Going ahead to step 2:
The number 797 fits into 87 0 times, leaving a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Fetch the next digit (6) from the dividend, attach it to 87 and continue: 876 / 797

Advancing to step 3:
When dividing 876 by 797, we get 1 with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 797 from 876 and we're left with 79.
Take the next digit (1) from the dividend and append it to 79, then repeat: 791 / 797

On to step 4:
When dividing 791 by 797, we get 0 with a remainder of 791.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 791 after subtracting 0 from 791.
Take the next digit (9) from the dividend and append it to 791, then repeat: 7919 / 797

On to step 5:
797 goes into 7919 9 times with a remainder of 746.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
If we take 7173 away from 7919, we end up with 746.
Append the next digit (4) from the dividend to 746 and continue with: 7464 / 797

Advancing to step 6:
When dividing 7464 by 797, we get 9 with a remainder of 291.
Use 9 as the next digit of our solution. 
Result so far: 1099.0
Subtracting 7173 from 7464 leaves us with 291.
Append the next digit (0) from the dividend to 291 and continue with: 2910 / 797

Advancing to step 7:
If we divide 2910 by 797, we get 3 and a remainder of 519.
Record the quotient 3 as the next digit in the result. 
Result so far: 10993.0
Deduct 2391 from 2910 and we're left with 519.
Bring next digit (3) of the dividend behind the 519 and repeat the process: 5193 / 797

On to step 8:
797 can be fit into 5193 6 times, resulting in a remainder of 411.
Write down 6 as next digit of the result. 
Result so far: 109936.0
Subtract 4782 from 5193 to get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Advancing to step 9:
797 goes into 4110 5 times with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 109936.5
The remainder is 125 after subtracting 3985 from 4110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 10:
797 goes into 1250 1 times with a remainder of 453.
Put 1 as the next digit of the answer. 
Result so far: 109936.51
If we subtract 797 from 1250, we get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Advancing to step 11:
The number 797 fits into 4530 5 times, leaving a remainder of 545.
Use 5 as the next digit of our solution. 
Result so far: 109936.515
If we take 3985 away from 4530, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

On to step 12:
5450 divided by 797 is 6 with a remainder of 668.
Write down 6 as next digit of the result. 
Result so far: 109936.5156
Subtract 4782 from 5450 to get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Let's proceed to step 13:
The number 797 fits into 6680 8 times, leaving a remainder of 304.
Write down 8 as next digit of the result. 
Result so far: 109936.51568
Subtract 6376 from 6680 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 14:
If we divide 3040 by 797, we get 3 and a remainder of 649.
The next digit of our result is 3. 
Result so far: 109936.515683
If we subtract 2391 from 3040, we get 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Advancing to step 15:
If we divide 6490 by 797, we get 8 and a remainder of 114.
The next digit of our result is 8. 
Result so far: 109936.5156838
If we take 6376 away from 6490, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 16:
When dividing 1140 by 797, we get 1 with a remainder of 343.
The next digit of our result is 1. 
Result so far: 109936.51568381
Subtracting 797 from 1140 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

After the division, we end up with 109936.51568381 and a remainder of 3.43e-07.
