Let's divide 21164020 by 959
The aim is to understand the frequency of 959 in 21164020.

Going ahead to step 1:
When dividing 2 by 959, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 959

Moving on to step 2:
21 divided by 959 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 959

Step 3:
The number 959 fits into 211 0 times, leaving a remainder of 211.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 211, we get 211.
Include the next digit (6) from the dividend after 211, then repeat: 2116 / 959

On to step 4:
959 can be fit into 2116 2 times, resulting in a remainder of 198.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1918 from 2116 and we're left with 198.
Bring next digit (4) of the dividend behind the 198 and repeat the process: 1984 / 959

Let's proceed to step 5:
959 can be fit into 1984 2 times, resulting in a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 1918 from 1984 to get 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 959

On to step 6:
If we divide 660 by 959, we get 0 and a remainder of 660.
Put 0 as the next digit of the answer. 
Result so far: 220.0
If we take 0 away from 660, we end up with 660.
Grab the next digit (2) from the dividend, add it to 660, then carry on: 6602 / 959

Moving on to step 7:
6602 divided by 959 is 6 with a remainder of 848.
The number 6 becomes the next digit in our result. 
Result so far: 2206.0
Subtract 5754 from 6602 to get 848.
Take the next digit (0) from the dividend and append it to 848, then repeat: 8480 / 959

Let's proceed to step 8:
The number 959 fits into 8480 8 times, leaving a remainder of 808.
Use 8 as the next digit of our solution. 
Result so far: 22068.0
Subtracting 7672 from 8480 leaves us with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Going ahead to step 9:
If we divide 8080 by 959, we get 8 and a remainder of 408.
Put 8 as the next digit of the answer. 
Result so far: 22068.8
Subtract 7672 from 8080 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 10:
959 goes into 4080 4 times with a remainder of 244.
Put 4 as the next digit of the answer. 
Result so far: 22068.84
If we subtract 3836 from 4080, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 11:
The number 959 fits into 2440 2 times, leaving a remainder of 522.
Write down 2 as next digit of the result. 
Result so far: 22068.842
Subtract 1918 from 2440 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Let's proceed to step 12:
The number 959 fits into 5220 5 times, leaving a remainder of 425.
Use 5 as the next digit of our solution. 
Result so far: 22068.8425
If we take 4795 away from 5220, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 13:
If we divide 4250 by 959, we get 4 and a remainder of 414.
The number 4 becomes the next digit in our result. 
Result so far: 22068.84254
Deduct 3836 from 4250 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 14:
When dividing 4140 by 959, we get 4 with a remainder of 304.
Use 4 as the next digit of our solution. 
Result so far: 22068.842544
If we subtract 3836 from 4140, we 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.

The quotient of the division is 22068.842544, and the remainder is 3.04e-05.
