We look at the division of 23367146 by 901 
The aim is to understand the frequency of 901 in 23367146.

On to step 1:
2 divided by 901 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 901

Moving on to step 2:
23 divided by 901 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 901

Moving on to step 3:
901 goes into 233 0 times with a remainder of 233.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 233, we get 233.
Grab the next digit (6) from the dividend, add it to 233, then carry on: 2336 / 901

Moving on to step 4:
When dividing 2336 by 901, we get 2 with a remainder of 534.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1802 away from 2336, we end up with 534.
Take the next digit (7) from the dividend and append it to 534, then repeat: 5347 / 901

Let's proceed to step 5:
901 goes into 5347 5 times with a remainder of 842.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 4505 from 5347 to get 842.
Take the next digit (1) from the dividend and append it to 842, then repeat: 8421 / 901

Advancing to step 6:
901 can be fit into 8421 9 times, resulting in a remainder of 312.
The number 9 becomes the next digit in our result. 
Result so far: 259.0
If we subtract 8109 from 8421, we get 312.
Include the next digit (4) from the dividend after 312, then repeat: 3124 / 901

Step 7:
901 can be fit into 3124 3 times, resulting in a remainder of 421.
Put 3 as the next digit of the answer. 
Result so far: 2593.0
If we subtract 2703 from 3124, we get 421.
Take the next digit (6) from the dividend and append it to 421, then repeat: 4216 / 901

Let's proceed to step 8:
901 can be fit into 4216 4 times, resulting in a remainder of 612.
Write down 4 as next digit of the result. 
Result so far: 25934.0
Subtract 3604 from 4216 to get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Advancing to step 9:
6120 divided by 901 is 6 with a remainder of 714.
Record the quotient 6 as the next digit in the result. 
Result so far: 25934.6
Subtract 5406 from 6120 to get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Moving on to step 10:
When dividing 7140 by 901, we get 7 with a remainder of 833.
The next digit of our result is 7. 
Result so far: 25934.67
Deduct 6307 from 7140 and we're left with 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

Moving on to step 11:
8330 divided by 901 is 9 with a remainder of 221.
Write down 9 as next digit of the result. 
Result so far: 25934.679
If we take 8109 away from 8330, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 12:
When dividing 2210 by 901, we get 2 with a remainder of 408.
The next digit of our result is 2. 
Result so far: 25934.6792
If we take 1802 away from 2210, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 13:
901 goes into 4080 4 times with a remainder of 476.
The number 4 becomes the next digit in our result. 
Result so far: 25934.67924
The remainder is 476 after subtracting 3604 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 14:
If we divide 4760 by 901, we get 5 and a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 25934.679245
The remainder is 255 after subtracting 4505 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 15:
If we divide 2550 by 901, we get 2 and a remainder of 748.
Write down 2 as next digit of the result. 
Result so far: 25934.6792452
Deduct 1802 from 2550 and we're left with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Moving on to step 16:
When dividing 7480 by 901, we get 8 with a remainder of 272.
The next digit of our result is 8. 
Result so far: 25934.67924528
If we subtract 7208 from 7480, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The quotient of the division is 25934.67924528, and the remainder is 2.72e-07.
