53003013 divided by 181 
The aim is to understand the frequency of 181 in 53003013.

Going ahead to step 1:
If we divide 5 by 181, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 181

On to step 2:
The number 181 fits into 53 0 times, leaving a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (0) from the dividend after 53, then repeat: 530 / 181

Going ahead to step 3:
If we divide 530 by 181, we get 2 and a remainder of 168.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 362 from 530, we get 168.
Append the next digit (0) from the dividend to 168 and continue with: 1680 / 181

Let's proceed to step 4:
1680 divided by 181 is 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 51 after subtracting 1629 from 1680.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 181

On to step 5:
513 divided by 181 is 2 with a remainder of 151.
Put 2 as the next digit of the answer. 
Result so far: 292.0
The remainder is 151 after subtracting 362 from 513.
Bring next digit (0) of the dividend behind the 151 and repeat the process: 1510 / 181

Going ahead to step 6:
1510 divided by 181 is 8 with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 2928.0
If we subtract 1448 from 1510, we get 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 181

Let's proceed to step 7:
When dividing 621 by 181, we get 3 with a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 29283.0
If we subtract 543 from 621, we get 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 181

Moving on to step 8:
783 divided by 181 is 4 with a remainder of 59.
Use 4 as the next digit of our solution. 
Result so far: 292834.0
Subtract 724 from 783 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 9:
If we divide 590 by 181, we get 3 and a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 292834.3
If we subtract 543 from 590, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 10:
When dividing 470 by 181, we get 2 with a remainder of 108.
The next digit of our result is 2. 
Result so far: 292834.32
The remainder is 108 after subtracting 362 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 11:
If we divide 1080 by 181, we get 5 and a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 292834.325
Subtracting 905 from 1080 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 12:
The number 181 fits into 1750 9 times, leaving a remainder of 121.
The next digit of our result is 9. 
Result so far: 292834.3259
Deduct 1629 from 1750 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 13:
1210 divided by 181 is 6 with a remainder of 124.
Put 6 as the next digit of the answer. 
Result so far: 292834.32596
If we subtract 1086 from 1210, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 14:
The number 181 fits into 1240 6 times, leaving a remainder of 154.
Use 6 as the next digit of our solution. 
Result so far: 292834.325966
Deduct 1086 from 1240 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final result is 292834.325966 with a remainder of 1.54e-05.
