We look at the division of 29435219 by 772 
The aim is to understand the frequency of 772 in 29435219.

Step 1:
The number 772 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 772

Going ahead to step 2:
If we divide 29 by 772, we get 0 and a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 772

Moving on to step 3:
772 can be fit into 294 0 times, resulting in a remainder of 294.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 294 and we're left with 294.
Grab the next digit (3) from the dividend, add it to 294, then carry on: 2943 / 772

On to step 4:
772 goes into 2943 3 times with a remainder of 627.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 2316 from 2943 leaves us with 627.
Append the next digit (5) from the dividend to 627 and continue with: 6275 / 772

Moving on to step 5:
The number 772 fits into 6275 8 times, leaving a remainder of 99.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 6176 from 6275 and we're left with 99.
Grab the next digit (2) from the dividend, add it to 99, then carry on: 992 / 772

Step 6:
772 can be fit into 992 1 times, resulting in a remainder of 220.
Record the quotient 1 as the next digit in the result. 
Result so far: 381.0
If we take 772 away from 992, we end up with 220.
Grab the next digit (1) from the dividend, add it to 220, then carry on: 2201 / 772

Moving on to step 7:
772 can be fit into 2201 2 times, resulting in a remainder of 657.
Record the quotient 2 as the next digit in the result. 
Result so far: 3812.0
Subtracting 1544 from 2201 leaves us with 657.
Append the next digit (9) from the dividend to 657 and continue with: 6579 / 772

Going ahead to step 8:
When dividing 6579 by 772, we get 8 with a remainder of 403.
Use 8 as the next digit of our solution. 
Result so far: 38128.0
If we subtract 6176 from 6579, we get 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Advancing to step 9:
772 can be fit into 4030 5 times, resulting in a remainder of 170.
Use 5 as the next digit of our solution. 
Result so far: 38128.5
If we take 3860 away from 4030, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
When dividing 1700 by 772, we get 2 with a remainder of 156.
The next digit of our result is 2. 
Result so far: 38128.52
Deduct 1544 from 1700 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 11:
When dividing 1560 by 772, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 38128.522
If we subtract 1544 from 1560, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 38128.522, with a leftover of 0.0016.
