40051616 ÷ 971 
The aim is to understand the frequency of 971 in 40051616.

Going ahead to step 1:
4 divided by 971 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 971

On to step 2:
971 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 971

Step 3:
If we divide 400 by 971, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 400 after subtracting 0 from 400.
Append the next digit (5) from the dividend to 400 and continue with: 4005 / 971

Step 4:
4005 divided by 971 is 4 with a remainder of 121.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 3884 from 4005 to get 121.
Grab the next digit (1) from the dividend, add it to 121, then carry on: 1211 / 971

Let's proceed to step 5:
971 can be fit into 1211 1 times, resulting in a remainder of 240.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtract 971 from 1211 to get 240.
Append the next digit (6) from the dividend to 240 and continue with: 2406 / 971

Moving on to step 6:
971 goes into 2406 2 times with a remainder of 464.
Write down 2 as next digit of the result. 
Result so far: 412.0
Deduct 1942 from 2406 and we're left with 464.
Fetch the next digit (1) from the dividend, attach it to 464 and continue: 4641 / 971

Step 7:
When dividing 4641 by 971, we get 4 with a remainder of 757.
Put 4 as the next digit of the answer. 
Result so far: 4124.0
Subtracting 3884 from 4641 leaves us with 757.
Take the next digit (6) from the dividend and append it to 757, then repeat: 7576 / 971

Let's proceed to step 8:
The number 971 fits into 7576 7 times, leaving a remainder of 779.
The number 7 becomes the next digit in our result. 
Result so far: 41247.0
Deduct 6797 from 7576 and we're left with 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

On to step 9:
7790 divided by 971 is 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 41247.8
Subtracting 7768 from 7790 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
If we divide 220 by 971, we get 0 and a remainder of 220.
The next digit of our result is 0. 
Result so far: 41247.8
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 11:
971 can be fit into 2200 2 times, resulting in a remainder of 258.
The number 2 becomes the next digit in our result. 
Result so far: 41247.802
Subtract 1942 from 2200 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 12:
The number 971 fits into 2580 2 times, leaving a remainder of 638.
Record the quotient 2 as the next digit in the result. 
Result so far: 41247.8022
Subtracting 1942 from 2580 leaves us with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

The final outcome is 41247.8022, with a leftover of 0.00638.
