We look at the division of 2971885 by 799 
The aim is to understand the frequency of 799 in 2971885.

Moving on to step 1:
The number 799 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 799

On to step 2:
The number 799 fits into 29 0 times, leaving a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 799

Going ahead to step 3:
When dividing 297 by 799, we get 0 with a remainder of 297.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 297, we get 297.
Bring next digit (1) of the dividend behind the 297 and repeat the process: 2971 / 799

Moving on to step 4:
When dividing 2971 by 799, we get 3 with a remainder of 574.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2397 from 2971 and we're left with 574.
Append the next digit (8) from the dividend to 574 and continue with: 5748 / 799

Step 5:
799 goes into 5748 7 times with a remainder of 155.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we take 5593 away from 5748, we end up with 155.
Bring next digit (8) of the dividend behind the 155 and repeat the process: 1558 / 799

Advancing to step 6:
799 can be fit into 1558 1 times, resulting in a remainder of 759.
Record the quotient 1 as the next digit in the result. 
Result so far: 371.0
Deduct 799 from 1558 and we're left with 759.
Take the next digit (5) from the dividend and append it to 759, then repeat: 7595 / 799

Moving on to step 7:
799 goes into 7595 9 times with a remainder of 404.
The number 9 becomes the next digit in our result. 
Result so far: 3719.0
Subtracting 7191 from 7595 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 8:
The number 799 fits into 4040 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 3719.5
Subtracting 3995 from 4040 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
When dividing 450 by 799, we get 0 with a remainder of 450.
The number 0 becomes the next digit in our result. 
Result so far: 3719.5
Deduct 0 from 450 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 10:
799 can be fit into 4500 5 times, resulting in a remainder of 505.
Use 5 as the next digit of our solution. 
Result so far: 3719.505
Subtracting 3995 from 4500 leaves us with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 11:
When dividing 5050 by 799, we get 6 with a remainder of 256.
The next digit of our result is 6. 
Result so far: 3719.5056
If we take 4794 away from 5050, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 12:
If we divide 2560 by 799, we get 3 and a remainder of 163.
The number 3 becomes the next digit in our result. 
Result so far: 3719.50563
If we take 2397 away from 2560, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 13:
If we divide 1630 by 799, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 3719.505632
Subtracting 1598 from 1630 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
320 divided by 799 is 0 with a remainder of 320.
The next digit of our result is 0. 
Result so far: 3719.505632
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
The number 799 fits into 3200 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 3719.50563204
If we take 3196 away from 3200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 3719.50563204 and a remainder of 4e-09.
