We look at the division of 29457753 by 851 
The aim is to understand the frequency of 851 in 29457753.

Going ahead to step 1:
2 divided by 851 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 851

Moving on to step 2:
If we divide 29 by 851, we get 0 and a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 851

Let's proceed to step 3:
851 goes into 294 0 times with a remainder of 294.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 294 to get 294.
Include the next digit (5) from the dividend after 294, then repeat: 2945 / 851

Let's proceed to step 4:
The number 851 fits into 2945 3 times, leaving a remainder of 392.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 2553 away from 2945, we end up with 392.
Append the next digit (7) from the dividend to 392 and continue with: 3927 / 851

Let's proceed to step 5:
When dividing 3927 by 851, we get 4 with a remainder of 523.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we subtract 3404 from 3927, we get 523.
Fetch the next digit (7) from the dividend, attach it to 523 and continue: 5237 / 851

Step 6:
If we divide 5237 by 851, we get 6 and a remainder of 131.
Record the quotient 6 as the next digit in the result. 
Result so far: 346.0
Deduct 5106 from 5237 and we're left with 131.
Grab the next digit (5) from the dividend, add it to 131, then carry on: 1315 / 851

Let's proceed to step 7:
851 can be fit into 1315 1 times, resulting in a remainder of 464.
Record the quotient 1 as the next digit in the result. 
Result so far: 3461.0
Subtract 851 from 1315 to get 464.
Bring next digit (3) of the dividend behind the 464 and repeat the process: 4643 / 851

Moving on to step 8:
4643 divided by 851 is 5 with a remainder of 388.
The next digit of our result is 5. 
Result so far: 34615.0
If we take 4255 away from 4643, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 9:
If we divide 3880 by 851, we get 4 and a remainder of 476.
Record the quotient 4 as the next digit in the result. 
Result so far: 34615.4
The remainder is 476 after subtracting 3404 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 10:
851 goes into 4760 5 times with a remainder of 505.
The next digit of our result is 5. 
Result so far: 34615.45
The remainder is 505 after subtracting 4255 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Advancing to step 11:
5050 divided by 851 is 5 with a remainder of 795.
Write down 5 as next digit of the result. 
Result so far: 34615.455
If we subtract 4255 from 5050, we get 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

The final outcome is 34615.455, with a leftover of 0.0795.
