Let's divide 18710831 by 601
The aim is to understand the frequency of 601 in 18710831.

Step 1:
The number 601 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 601

Going ahead to step 2:
601 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 601

Moving on to step 3:
601 can be fit into 187 0 times, resulting in a remainder of 187.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 187 leaves us with 187.
Fetch the next digit (1) from the dividend, attach it to 187 and continue: 1871 / 601

Going ahead to step 4:
601 can be fit into 1871 3 times, resulting in a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 1803 from 1871, we get 68.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 601

Moving on to step 5:
680 divided by 601 is 1 with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we take 601 away from 680, we end up with 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 601

On to step 6:
The number 601 fits into 798 1 times, leaving a remainder of 197.
Write down 1 as next digit of the result. 
Result so far: 311.0
If we subtract 601 from 798, we get 197.
Take the next digit (3) from the dividend and append it to 197, then repeat: 1973 / 601

Moving on to step 7:
601 can be fit into 1973 3 times, resulting in a remainder of 170.
Write down 3 as next digit of the result. 
Result so far: 3113.0
Subtracting 1803 from 1973 leaves us with 170.
Append the next digit (1) from the dividend to 170 and continue with: 1701 / 601

Moving on to step 8:
The number 601 fits into 1701 2 times, leaving a remainder of 499.
The number 2 becomes the next digit in our result. 
Result so far: 31132.0
If we subtract 1202 from 1701, we get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Going ahead to step 9:
601 can be fit into 4990 8 times, resulting in a remainder of 182.
Put 8 as the next digit of the answer. 
Result so far: 31132.8
The remainder is 182 after subtracting 4808 from 4990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 10:
1820 divided by 601 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 31132.83
The remainder is 17 after subtracting 1803 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
If we divide 170 by 601, we get 0 and a remainder of 170.
The next digit of our result is 0. 
Result so far: 31132.83
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 12:
601 goes into 1700 2 times with a remainder of 498.
Write down 2 as next digit of the result. 
Result so far: 31132.8302
If we subtract 1202 from 1700, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Step 13:
When dividing 4980 by 601, we get 8 with a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 31132.83028
Subtract 4808 from 4980 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 14:
601 can be fit into 1720 2 times, resulting in a remainder of 518.
The next digit of our result is 2. 
Result so far: 31132.830282
If we take 1202 away from 1720, we end up with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Moving on to step 15:
If we divide 5180 by 601, we get 8 and a remainder of 372.
Use 8 as the next digit of our solution. 
Result so far: 31132.8302828
Subtract 4808 from 5180 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 16:
If we divide 3720 by 601, we get 6 and a remainder of 114.
Put 6 as the next digit of the answer. 
Result so far: 31132.83028286
If we take 3606 away from 3720, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The quotient of the division is 31132.83028286, and the remainder is 1.14e-07.
