Let's divide 71590833 by 981
The aim is to understand the frequency of 981 in 71590833.

On to step 1:
7 divided by 981 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
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 / 981

On to step 2:
981 goes into 71 0 times with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 981

Advancing to step 3:
If we divide 715 by 981, we get 0 and a remainder of 715.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 715 leaves us with 715.
Include the next digit (9) from the dividend after 715, then repeat: 7159 / 981

Step 4:
7159 divided by 981 is 7 with a remainder of 292.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 6867 from 7159 and we're left with 292.
Take the next digit (0) from the dividend and append it to 292, then repeat: 2920 / 981

Step 5:
2920 divided by 981 is 2 with a remainder of 958.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtract 1962 from 2920 to get 958.
Append the next digit (8) from the dividend to 958 and continue with: 9588 / 981

Advancing to step 6:
If we divide 9588 by 981, we get 9 and a remainder of 759.
The next digit of our result is 9. 
Result so far: 729.0
The remainder is 759 after subtracting 8829 from 9588.
Take the next digit (3) from the dividend and append it to 759, then repeat: 7593 / 981

Let's proceed to step 7:
7593 divided by 981 is 7 with a remainder of 726.
The number 7 becomes the next digit in our result. 
Result so far: 7297.0
Subtracting 6867 from 7593 leaves us with 726.
Grab the next digit (3) from the dividend, add it to 726, then carry on: 7263 / 981

Going ahead to step 8:
When dividing 7263 by 981, we get 7 with a remainder of 396.
Use 7 as the next digit of our solution. 
Result so far: 72977.0
Subtract 6867 from 7263 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 9:
If we divide 3960 by 981, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 72977.4
Subtract 3924 from 3960 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
981 goes into 360 0 times with a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 72977.4
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
When dividing 3600 by 981, we get 3 with a remainder of 657.
Write down 3 as next digit of the result. 
Result so far: 72977.403
Subtracting 2943 from 3600 leaves us with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Step 12:
When dividing 6570 by 981, we get 6 with a remainder of 684.
The number 6 becomes the next digit in our result. 
Result so far: 72977.4036
If we take 5886 away from 6570, we end up with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Step 13:
When dividing 6840 by 981, we get 6 with a remainder of 954.
Record the quotient 6 as the next digit in the result. 
Result so far: 72977.40366
If we subtract 5886 from 6840, we get 954.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9540, and continue the process.

The quotient of the division is 72977.40366, and the remainder is 0.000954.
