We look at the division of 91883946 by 29 
The aim is to understand the frequency of 29 in 91883946.

On to step 1:
The number 29 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 29

Going ahead to step 2:
91 divided by 29 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 87 from 91, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 29

Step 3:
When dividing 48 by 29, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 19 after subtracting 29 from 48.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 29

Step 4:
When dividing 198 by 29, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 316.0
If we subtract 174 from 198, we get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 29

Going ahead to step 5:
When dividing 243 by 29, we get 8 with a remainder of 11.
The next digit of our result is 8. 
Result so far: 3168.0
Deduct 232 from 243 and we're left with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 29

Going ahead to step 6:
29 goes into 119 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 31684.0
Subtract 116 from 119 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 29

Moving on to step 7:
29 can be fit into 34 1 times, resulting in a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 316841.0
Subtract 29 from 34 to get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 29

Advancing to step 8:
If we divide 56 by 29, we get 1 and a remainder of 27.
The next digit of our result is 1. 
Result so far: 3168411.0
Subtract 29 from 56 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
29 goes into 270 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 3168411.9
Subtract 261 from 270 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
When dividing 90 by 29, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3168411.93
Subtract 87 from 90 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
29 can be fit into 30 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 3168411.931
Subtracting 29 from 30 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
If we divide 10 by 29, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 3168411.931
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
29 goes into 100 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3168411.93103
The remainder is 13 after subtracting 87 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 14:
130 divided by 29 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 3168411.931034
The remainder is 14 after subtracting 116 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 15:
If we divide 140 by 29, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 3168411.9310344
Subtracting 116 from 140 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 3168411.9310344 with a remaining 2.4e-07.
