87806919 divided by 926 
The aim is to understand the frequency of 926 in 87806919.

On to step 1:
When dividing 8 by 926, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 926

Let's proceed to step 2:
The number 926 fits into 87 0 times, leaving a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Bring next digit (8) of the dividend behind the 87 and repeat the process: 878 / 926

Let's proceed to step 3:
878 divided by 926 is 0 with a remainder of 878.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 878 and we're left with 878.
Take the next digit (0) from the dividend and append it to 878, then repeat: 8780 / 926

Moving on to step 4:
The number 926 fits into 8780 9 times, leaving a remainder of 446.
The next digit of our result is 9. 
Result so far: 9.0
If we take 8334 away from 8780, we end up with 446.
Include the next digit (6) from the dividend after 446, then repeat: 4466 / 926

Step 5:
The number 926 fits into 4466 4 times, leaving a remainder of 762.
Put 4 as the next digit of the answer. 
Result so far: 94.0
Subtract 3704 from 4466 to get 762.
Bring next digit (9) of the dividend behind the 762 and repeat the process: 7629 / 926

Advancing to step 6:
926 can be fit into 7629 8 times, resulting in a remainder of 221.
The next digit of our result is 8. 
Result so far: 948.0
The remainder is 221 after subtracting 7408 from 7629.
Bring next digit (1) of the dividend behind the 221 and repeat the process: 2211 / 926

Going ahead to step 7:
When dividing 2211 by 926, we get 2 with a remainder of 359.
Write down 2 as next digit of the result. 
Result so far: 9482.0
Subtract 1852 from 2211 to get 359.
Bring next digit (9) of the dividend behind the 359 and repeat the process: 3599 / 926

On to step 8:
3599 divided by 926 is 3 with a remainder of 821.
Write down 3 as next digit of the result. 
Result so far: 94823.0
Subtracting 2778 from 3599 leaves us with 821.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

Moving on to step 9:
926 goes into 8210 8 times with a remainder of 802.
Write down 8 as next digit of the result. 
Result so far: 94823.8
The remainder is 802 after subtracting 7408 from 8210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Step 10:
When dividing 8020 by 926, we get 8 with a remainder of 612.
The number 8 becomes the next digit in our result. 
Result so far: 94823.88
If we take 7408 away from 8020, we end up with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

The final result is 94823.88 with a remainder of 0.612.
