Let's divide 81201690 by 956
The aim is to understand the frequency of 956 in 81201690.

Going ahead to step 1:
When dividing 8 by 956, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 956

Going ahead to step 2:
81 divided by 956 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 956

Step 3:
956 can be fit into 812 0 times, resulting in a remainder of 812.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 812, we get 812.
Append the next digit (0) from the dividend to 812 and continue with: 8120 / 956

Step 4:
956 goes into 8120 8 times with a remainder of 472.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 7648 away from 8120, we end up with 472.
Append the next digit (1) from the dividend to 472 and continue with: 4721 / 956

Advancing to step 5:
When dividing 4721 by 956, we get 4 with a remainder of 897.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtracting 3824 from 4721 leaves us with 897.
Bring next digit (6) of the dividend behind the 897 and repeat the process: 8976 / 956

Advancing to step 6:
956 can be fit into 8976 9 times, resulting in a remainder of 372.
Write down 9 as next digit of the result. 
Result so far: 849.0
If we take 8604 away from 8976, we end up with 372.
Include the next digit (9) from the dividend after 372, then repeat: 3729 / 956

On to step 7:
If we divide 3729 by 956, we get 3 and a remainder of 861.
Record the quotient 3 as the next digit in the result. 
Result so far: 8493.0
Deduct 2868 from 3729 and we're left with 861.
Append the next digit (0) from the dividend to 861 and continue with: 8610 / 956

On to step 8:
The number 956 fits into 8610 9 times, leaving a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 84939.0
Subtract 8604 from 8610 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
The number 956 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 84939.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
When dividing 600 by 956, we get 0 with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 84939.0
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The quotient of the division is 84939.0, and the remainder is 0.6.
