57351225 ÷ 191 
The aim is to understand the frequency of 191 in 57351225.

Advancing to step 1:
If we divide 5 by 191, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 191

Going ahead to step 2:
The number 191 fits into 57 0 times, leaving a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Append the next digit (3) from the dividend to 57 and continue with: 573 / 191

Advancing to step 3:
If we divide 573 by 191, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 573 from 573 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 191

Going ahead to step 4:
191 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 191

On to step 5:
191 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 300.0
If we subtract 0 from 51, we get 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 191

Let's proceed to step 6:
512 divided by 191 is 2 with a remainder of 130.
Write down 2 as next digit of the result. 
Result so far: 3002.0
If we take 382 away from 512, we end up with 130.
Append the next digit (2) from the dividend to 130 and continue with: 1302 / 191

Step 7:
191 can be fit into 1302 6 times, resulting in a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 30026.0
Subtract 1146 from 1302 to get 156.
Append the next digit (5) from the dividend to 156 and continue with: 1565 / 191

Going ahead to step 8:
When dividing 1565 by 191, we get 8 with a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 300268.0
If we take 1528 away from 1565, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
If we divide 370 by 191, we get 1 and a remainder of 179.
Use 1 as the next digit of our solution. 
Result so far: 300268.1
If we subtract 191 from 370, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 10:
If we divide 1790 by 191, we get 9 and a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 300268.19
If we subtract 1719 from 1790, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 11:
191 can be fit into 710 3 times, resulting in a remainder of 137.
Use 3 as the next digit of our solution. 
Result so far: 300268.193
If we subtract 573 from 710, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 12:
If we divide 1370 by 191, we get 7 and a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 300268.1937
Subtracting 1337 from 1370 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 13:
If we divide 330 by 191, we get 1 and a remainder of 139.
The next digit of our result is 1. 
Result so far: 300268.19371
The remainder is 139 after subtracting 191 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 14:
1390 divided by 191 is 7 with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 300268.193717
If we take 1337 away from 1390, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 15:
191 goes into 530 2 times with a remainder of 148.
Write down 2 as next digit of the result. 
Result so far: 300268.1937172
If we take 382 away from 530, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 16:
If we divide 1480 by 191, we get 7 and a remainder of 143.
The number 7 becomes the next digit in our result. 
Result so far: 300268.19371727
If we take 1337 away from 1480, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

The final result is 300268.19371727 with a remainder of 1.43e-07.
