We look at the division of 29971451 by 856 
The aim is to understand the frequency of 856 in 29971451.

Advancing to step 1:
When dividing 2 by 856, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 856

Step 2:
The number 856 fits into 29 0 times, leaving a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 856

On to step 3:
856 can be fit into 299 0 times, resulting in a remainder of 299.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 299, we get 299.
Grab the next digit (7) from the dividend, add it to 299, then carry on: 2997 / 856

Let's proceed to step 4:
The number 856 fits into 2997 3 times, leaving a remainder of 429.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 2568 from 2997 to get 429.
Grab the next digit (1) from the dividend, add it to 429, then carry on: 4291 / 856

Step 5:
When dividing 4291 by 856, we get 5 with a remainder of 11.
The next digit of our result is 5. 
Result so far: 35.0
Subtracting 4280 from 4291 leaves us with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 856

On to step 6:
114 divided by 856 is 0 with a remainder of 114.
The number 0 becomes the next digit in our result. 
Result so far: 350.0
Deduct 0 from 114 and we're left with 114.
Append the next digit (5) from the dividend to 114 and continue with: 1145 / 856

Step 7:
When dividing 1145 by 856, we get 1 with a remainder of 289.
The number 1 becomes the next digit in our result. 
Result so far: 3501.0
Deduct 856 from 1145 and we're left with 289.
Fetch the next digit (1) from the dividend, attach it to 289 and continue: 2891 / 856

On to step 8:
The number 856 fits into 2891 3 times, leaving a remainder of 323.
Use 3 as the next digit of our solution. 
Result so far: 35013.0
Deduct 2568 from 2891 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 9:
If we divide 3230 by 856, we get 3 and a remainder of 662.
Use 3 as the next digit of our solution. 
Result so far: 35013.3
Deduct 2568 from 3230 and we're left with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 10:
856 can be fit into 6620 7 times, resulting in a remainder of 628.
Write down 7 as next digit of the result. 
Result so far: 35013.37
Subtract 5992 from 6620 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Advancing to step 11:
856 goes into 6280 7 times with a remainder of 288.
Use 7 as the next digit of our solution. 
Result so far: 35013.377
The remainder is 288 after subtracting 5992 from 6280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The quotient of the division is 35013.377, and the remainder is 0.0288.
