We divide 3187507 by 911
The aim is to understand the frequency of 911 in 3187507.

Step 1:
When dividing 3 by 911, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 911

Going ahead to step 2:
31 divided by 911 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 911

Moving on to step 3:
911 can be fit into 318 0 times, resulting in a remainder of 318.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 318, we get 318.
Fetch the next digit (7) from the dividend, attach it to 318 and continue: 3187 / 911

Moving on to step 4:
The number 911 fits into 3187 3 times, leaving a remainder of 454.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 2733 from 3187 to get 454.
Include the next digit (5) from the dividend after 454, then repeat: 4545 / 911

Let's proceed to step 5:
If we divide 4545 by 911, we get 4 and a remainder of 901.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
The remainder is 901 after subtracting 3644 from 4545.
Grab the next digit (0) from the dividend, add it to 901, then carry on: 9010 / 911

Moving on to step 6:
911 can be fit into 9010 9 times, resulting in a remainder of 811.
Put 9 as the next digit of the answer. 
Result so far: 349.0
If we subtract 8199 from 9010, we get 811.
Take the next digit (7) from the dividend and append it to 811, then repeat: 8117 / 911

Let's proceed to step 7:
8117 divided by 911 is 8 with a remainder of 829.
Write down 8 as next digit of the result. 
Result so far: 3498.0
If we subtract 7288 from 8117, we get 829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8290, and continue the process.

Going ahead to step 8:
911 can be fit into 8290 9 times, resulting in a remainder of 91.
The number 9 becomes the next digit in our result. 
Result so far: 3498.9
If we take 8199 away from 8290, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 9:
911 goes into 910 0 times with a remainder of 910.
The next digit of our result is 0. 
Result so far: 3498.9
If we take 0 away from 910, we end up with 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

Going ahead to step 10:
911 goes into 9100 9 times with a remainder of 901.
The number 9 becomes the next digit in our result. 
Result so far: 3498.909
If we subtract 8199 from 9100, we get 901.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9010, and continue the process.

Step 11:
911 goes into 9010 9 times with a remainder of 811.
Put 9 as the next digit of the answer. 
Result so far: 3498.9099
The remainder is 811 after subtracting 8199 from 9010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

The final outcome is 3498.9099, with a leftover of 0.00811.
