We look at the division of 9938626 by 905 
The aim is to understand the frequency of 905 in 9938626.

Let's proceed to step 1:
905 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 905

Let's proceed to step 2:
905 can be fit into 99 0 times, resulting in a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Fetch the next digit (3) from the dividend, attach it to 99 and continue: 993 / 905

Let's proceed to step 3:
When dividing 993 by 905, we get 1 with a remainder of 88.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 905 from 993 and we're left with 88.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 905

On to step 4:
905 can be fit into 888 0 times, resulting in a remainder of 888.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 888 leaves us with 888.
Grab the next digit (6) from the dividend, add it to 888, then carry on: 8886 / 905

Going ahead to step 5:
905 can be fit into 8886 9 times, resulting in a remainder of 741.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Deduct 8145 from 8886 and we're left with 741.
Grab the next digit (2) from the dividend, add it to 741, then carry on: 7412 / 905

Going ahead to step 6:
905 can be fit into 7412 8 times, resulting in a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 1098.0
Subtract 7240 from 7412 to get 172.
Append the next digit (6) from the dividend to 172 and continue with: 1726 / 905

Moving on to step 7:
1726 divided by 905 is 1 with a remainder of 821.
Use 1 as the next digit of our solution. 
Result so far: 10981.0
Deduct 905 from 1726 and we're left with 821.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

Going ahead to step 8:
8210 divided by 905 is 9 with a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 10981.9
Subtract 8145 from 8210 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
The number 905 fits into 650 0 times, leaving a remainder of 650.
Use 0 as the next digit of our solution. 
Result so far: 10981.9
The remainder is 650 after subtracting 0 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 10:
905 can be fit into 6500 7 times, resulting in a remainder of 165.
The number 7 becomes the next digit in our result. 
Result so far: 10981.907
Subtract 6335 from 6500 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 11:
When dividing 1650 by 905, we get 1 with a remainder of 745.
The number 1 becomes the next digit in our result. 
Result so far: 10981.9071
Subtract 905 from 1650 to get 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Step 12:
905 can be fit into 7450 8 times, resulting in a remainder of 210.
Record the quotient 8 as the next digit in the result. 
Result so far: 10981.90718
Subtracting 7240 from 7450 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 13:
When dividing 2100 by 905, we get 2 with a remainder of 290.
Record the quotient 2 as the next digit in the result. 
Result so far: 10981.907182
The remainder is 290 after subtracting 1810 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 14:
2900 divided by 905 is 3 with a remainder of 185.
Use 3 as the next digit of our solution. 
Result so far: 10981.9071823
Subtract 2715 from 2900 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 15:
905 can be fit into 1850 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 10981.90718232
Deduct 1810 from 1850 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 10981.90718232 with a remaining 4e-08.
