78905631 ÷ 191 
The aim is to understand the frequency of 191 in 78905631.

Step 1:
When dividing 7 by 191, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 191

Advancing to step 2:
191 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 191

Let's proceed to step 3:
When dividing 789 by 191, we get 4 with a remainder of 25.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 764 from 789 leaves us with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 191

Moving on to step 4:
If we divide 250 by 191, we get 1 and a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we take 191 away from 250, we end up with 59.
Fetch the next digit (5) from the dividend, attach it to 59 and continue: 595 / 191

Step 5:
If we divide 595 by 191, we get 3 and a remainder of 22.
The next digit of our result is 3. 
Result so far: 413.0
The remainder is 22 after subtracting 573 from 595.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 191

Let's proceed to step 6:
If we divide 226 by 191, we get 1 and a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 4131.0
If we subtract 191 from 226, we get 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 191

On to step 7:
353 divided by 191 is 1 with a remainder of 162.
Write down 1 as next digit of the result. 
Result so far: 41311.0
Deduct 191 from 353 and we're left with 162.
Include the next digit (1) from the dividend after 162, then repeat: 1621 / 191

On to step 8:
191 can be fit into 1621 8 times, resulting in a remainder of 93.
Use 8 as the next digit of our solution. 
Result so far: 413118.0
The remainder is 93 after subtracting 1528 from 1621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 9:
191 can be fit into 930 4 times, resulting in a remainder of 166.
The next digit of our result is 4. 
Result so far: 413118.4
Subtracting 764 from 930 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 10:
191 can be fit into 1660 8 times, resulting in a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 413118.48
If we take 1528 away from 1660, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 11:
When dividing 1320 by 191, we get 6 with a remainder of 174.
Use 6 as the next digit of our solution. 
Result so far: 413118.486
The remainder is 174 after subtracting 1146 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 12:
When dividing 1740 by 191, we get 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 413118.4869
The remainder is 21 after subtracting 1719 from 1740.
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 13:
If we divide 210 by 191, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 413118.48691
Deduct 191 from 210 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 14:
191 can be fit into 190 0 times, resulting in a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 413118.48691
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 15:
The number 191 fits into 1900 9 times, leaving a remainder of 181.
The next digit of our result is 9. 
Result so far: 413118.4869109
The remainder is 181 after subtracting 1719 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 16:
If we divide 1810 by 191, we get 9 and a remainder of 91.
Put 9 as the next digit of the answer. 
Result so far: 413118.48691099
The remainder is 91 after subtracting 1719 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

In conclusion, the division gives 413118.48691099 with a balance of 9.1e-08.
