We're dividing 71136102 by 397 
The aim is to understand the frequency of 397 in 71136102.

Moving on to step 1:
7 divided by 397 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 397

Advancing to step 2:
The number 397 fits into 71 0 times, leaving a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 397

On to step 3:
If we divide 711 by 397, we get 1 and a remainder of 314.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 314 after subtracting 397 from 711.
Grab the next digit (3) from the dividend, add it to 314, then carry on: 3143 / 397

Going ahead to step 4:
The number 397 fits into 3143 7 times, leaving a remainder of 364.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 2779 from 3143 to get 364.
Take the next digit (6) from the dividend and append it to 364, then repeat: 3646 / 397

Step 5:
397 can be fit into 3646 9 times, resulting in a remainder of 73.
Use 9 as the next digit of our solution. 
Result so far: 179.0
The remainder is 73 after subtracting 3573 from 3646.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 397

Let's proceed to step 6:
397 can be fit into 731 1 times, resulting in a remainder of 334.
Write down 1 as next digit of the result. 
Result so far: 1791.0
If we subtract 397 from 731, we get 334.
Append the next digit (0) from the dividend to 334 and continue with: 3340 / 397

Step 7:
397 goes into 3340 8 times with a remainder of 164.
The next digit of our result is 8. 
Result so far: 17918.0
The remainder is 164 after subtracting 3176 from 3340.
Append the next digit (2) from the dividend to 164 and continue with: 1642 / 397

Step 8:
397 can be fit into 1642 4 times, resulting in a remainder of 54.
The next digit of our result is 4. 
Result so far: 179184.0
Deduct 1588 from 1642 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
540 divided by 397 is 1 with a remainder of 143.
Put 1 as the next digit of the answer. 
Result so far: 179184.1
Deduct 397 from 540 and we're left 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.

On to step 10:
The number 397 fits into 1430 3 times, leaving a remainder of 239.
Record the quotient 3 as the next digit in the result. 
Result so far: 179184.13
If we subtract 1191 from 1430, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 11:
2390 divided by 397 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 179184.136
If we take 2382 away from 2390, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
397 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 179184.136
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
800 divided by 397 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 179184.13602
Subtract 794 from 800 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
397 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 179184.13602
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 15:
397 can be fit into 600 1 times, resulting in a remainder of 203.
Record the quotient 1 as the next digit in the result. 
Result so far: 179184.1360201
If we subtract 397 from 600, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 16:
If we divide 2030 by 397, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 179184.13602015
Subtracting 1985 from 2030 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 179184.13602015 with a remaining 4.5e-08.
