30726685 ÷ 901 
The aim is to understand the frequency of 901 in 30726685.

Step 1:
901 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 901

Let's proceed to step 2:
When dividing 30 by 901, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 901

Going ahead to step 3:
901 goes into 307 0 times with a remainder of 307.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 307 and we're left with 307.
Bring next digit (2) of the dividend behind the 307 and repeat the process: 3072 / 901

Step 4:
If we divide 3072 by 901, we get 3 and a remainder of 369.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 2703 from 3072 to get 369.
Fetch the next digit (6) from the dividend, attach it to 369 and continue: 3696 / 901

On to step 5:
901 goes into 3696 4 times with a remainder of 92.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we take 3604 away from 3696, we end up with 92.
Take the next digit (6) from the dividend and append it to 92, then repeat: 926 / 901

Moving on to step 6:
If we divide 926 by 901, we get 1 and a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 341.0
If we subtract 901 from 926, we get 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 901

Advancing to step 7:
The number 901 fits into 258 0 times, leaving a remainder of 258.
Put 0 as the next digit of the answer. 
Result so far: 3410.0
Subtract 0 from 258 to get 258.
Bring next digit (5) of the dividend behind the 258 and repeat the process: 2585 / 901

Moving on to step 8:
When dividing 2585 by 901, we get 2 with a remainder of 783.
The next digit of our result is 2. 
Result so far: 34102.0
If we subtract 1802 from 2585, we get 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Advancing to step 9:
901 can be fit into 7830 8 times, resulting in a remainder of 622.
Put 8 as the next digit of the answer. 
Result so far: 34102.8
If we subtract 7208 from 7830, we get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Let's proceed to step 10:
6220 divided by 901 is 6 with a remainder of 814.
Use 6 as the next digit of our solution. 
Result so far: 34102.86
Subtracting 5406 from 6220 leaves us with 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Moving on to step 11:
If we divide 8140 by 901, we get 9 and a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 34102.869
If we take 8109 away from 8140, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 12:
When dividing 310 by 901, we get 0 with a remainder of 310.
The next digit of our result is 0. 
Result so far: 34102.869
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 13:
When dividing 3100 by 901, we get 3 with a remainder of 397.
Put 3 as the next digit of the answer. 
Result so far: 34102.86903
The remainder is 397 after subtracting 2703 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Moving on to step 14:
When dividing 3970 by 901, we get 4 with a remainder of 366.
Put 4 as the next digit of the answer. 
Result so far: 34102.869034
If we subtract 3604 from 3970, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 15:
If we divide 3660 by 901, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 34102.8690344
Subtract 3604 from 3660 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 34102.8690344 with a remaining 5.6e-07.
