We look at the division of 21956760 by 971 
The aim is to understand the frequency of 971 in 21956760.

On to step 1:
971 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 971

Going ahead to step 2:
971 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 971

Advancing to step 3:
971 goes into 219 0 times with a remainder of 219.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 219 leaves us with 219.
Bring next digit (5) of the dividend behind the 219 and repeat the process: 2195 / 971

Advancing to step 4:
If we divide 2195 by 971, we get 2 and a remainder of 253.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1942 from 2195, we get 253.
Include the next digit (6) from the dividend after 253, then repeat: 2536 / 971

Moving on to step 5:
The number 971 fits into 2536 2 times, leaving a remainder of 594.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 1942 from 2536, we get 594.
Grab the next digit (7) from the dividend, add it to 594, then carry on: 5947 / 971

Step 6:
971 goes into 5947 6 times with a remainder of 121.
Write down 6 as next digit of the result. 
Result so far: 226.0
Subtract 5826 from 5947 to get 121.
Grab the next digit (6) from the dividend, add it to 121, then carry on: 1216 / 971

Advancing to step 7:
1216 divided by 971 is 1 with a remainder of 245.
Write down 1 as next digit of the result. 
Result so far: 2261.0
Subtracting 971 from 1216 leaves us with 245.
Grab the next digit (0) from the dividend, add it to 245, then carry on: 2450 / 971

Advancing to step 8:
971 goes into 2450 2 times with a remainder of 508.
The number 2 becomes the next digit in our result. 
Result so far: 22612.0
If we subtract 1942 from 2450, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Advancing to step 9:
If we divide 5080 by 971, we get 5 and a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 22612.5
Deduct 4855 from 5080 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 10:
When dividing 2250 by 971, we get 2 with a remainder of 308.
Use 2 as the next digit of our solution. 
Result so far: 22612.52
If we take 1942 away from 2250, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 11:
When dividing 3080 by 971, we get 3 with a remainder of 167.
Put 3 as the next digit of the answer. 
Result so far: 22612.523
If we take 2913 away from 3080, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Let's proceed to step 12:
971 can be fit into 1670 1 times, resulting in a remainder of 699.
Put 1 as the next digit of the answer. 
Result so far: 22612.5231
Subtracting 971 from 1670 leaves us with 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Going ahead to step 13:
971 goes into 6990 7 times with a remainder of 193.
The next digit of our result is 7. 
Result so far: 22612.52317
Subtract 6797 from 6990 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Let's proceed to step 14:
971 goes into 1930 1 times with a remainder of 959.
Use 1 as the next digit of our solution. 
Result so far: 22612.523171
If we take 971 away from 1930, we end up with 959.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9590, and continue the process.

Let's proceed to step 15:
The number 971 fits into 9590 9 times, leaving a remainder of 851.
Record the quotient 9 as the next digit in the result. 
Result so far: 22612.5231719
If we subtract 8739 from 9590, we get 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

Step 16:
8510 divided by 971 is 8 with a remainder of 742.
Put 8 as the next digit of the answer. 
Result so far: 22612.52317198
Deduct 7768 from 8510 and we're left with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

After the division, we end up with 22612.52317198 and a remainder of 7.42e-07.
