91675807 ÷ 29 
The aim is to understand the frequency of 29 in 91675807.

On to step 1:
29 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 29

On to step 2:
The number 29 fits into 91 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 87 away from 91, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 29

Moving on to step 3:
If we divide 46 by 29, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 29 from 46 to get 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 29

Let's proceed to step 4:
When dividing 177 by 29, we get 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 316.0
If we take 174 away from 177, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 29

On to step 5:
When dividing 35 by 29, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 3161.0
Deduct 29 from 35 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 29

Moving on to step 6:
29 can be fit into 68 2 times, resulting in a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 31612.0
Deduct 58 from 68 and we're left with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 29

Going ahead to step 7:
When dividing 100 by 29, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 316123.0
If we take 87 away from 100, we end up with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 29

Let's proceed to step 8:
If we divide 137 by 29, we get 4 and a remainder of 21.
The next digit of our result is 4. 
Result so far: 3161234.0
If we take 116 away from 137, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
If we divide 210 by 29, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 3161234.7
If we take 203 away from 210, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
When dividing 70 by 29, we get 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 3161234.72
If we subtract 58 from 70, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
29 can be fit into 120 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 3161234.724
If we subtract 116 from 120, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
When dividing 40 by 29, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 3161234.7241
If we take 29 away from 40, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 13:
29 can be fit into 110 3 times, resulting in a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 3161234.72413
Subtract 87 from 110 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 14:
29 goes into 230 7 times with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 3161234.724137
If we take 203 away from 230, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 15:
The number 29 fits into 270 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 3161234.7241379
If we subtract 261 from 270, we 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.

On to step 16:
When dividing 90 by 29, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3161234.72413793
Deduct 87 from 90 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 3161234.72413793 with a remaining 3e-09.
