We look at the division of 19186898 by 906 
The aim is to understand the frequency of 906 in 19186898.

Advancing to step 1:
When dividing 1 by 906, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 906

Advancing to step 2:
19 divided by 906 is 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 906

Step 3:
906 goes into 191 0 times with a remainder of 191.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 191 to get 191.
Take the next digit (8) from the dividend and append it to 191, then repeat: 1918 / 906

Going ahead to step 4:
906 goes into 1918 2 times with a remainder of 106.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1812 from 1918, we get 106.
Take the next digit (6) from the dividend and append it to 106, then repeat: 1066 / 906

Step 5:
906 can be fit into 1066 1 times, resulting in a remainder of 160.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 906 from 1066, we get 160.
Take the next digit (8) from the dividend and append it to 160, then repeat: 1608 / 906

Advancing to step 6:
906 can be fit into 1608 1 times, resulting in a remainder of 702.
The number 1 becomes the next digit in our result. 
Result so far: 211.0
If we subtract 906 from 1608, we get 702.
Include the next digit (9) from the dividend after 702, then repeat: 7029 / 906

On to step 7:
7029 divided by 906 is 7 with a remainder of 687.
Write down 7 as next digit of the result. 
Result so far: 2117.0
The remainder is 687 after subtracting 6342 from 7029.
Append the next digit (8) from the dividend to 687 and continue with: 6878 / 906

Let's proceed to step 8:
The number 906 fits into 6878 7 times, leaving a remainder of 536.
Write down 7 as next digit of the result. 
Result so far: 21177.0
Subtracting 6342 from 6878 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Let's proceed to step 9:
906 can be fit into 5360 5 times, resulting in a remainder of 830.
Record the quotient 5 as the next digit in the result. 
Result so far: 21177.5
If we take 4530 away from 5360, we end up with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Let's proceed to step 10:
When dividing 8300 by 906, we get 9 with a remainder of 146.
Write down 9 as next digit of the result. 
Result so far: 21177.59
Subtracting 8154 from 8300 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 11:
906 can be fit into 1460 1 times, resulting in a remainder of 554.
Put 1 as the next digit of the answer. 
Result so far: 21177.591
Deduct 906 from 1460 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Advancing to step 12:
906 goes into 5540 6 times with a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 21177.5916
If we take 5436 away from 5540, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 13:
The number 906 fits into 1040 1 times, leaving a remainder of 134.
The number 1 becomes the next digit in our result. 
Result so far: 21177.59161
Subtracting 906 from 1040 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 14:
1340 divided by 906 is 1 with a remainder of 434.
Put 1 as the next digit of the answer. 
Result so far: 21177.591611
If we take 906 away from 1340, we end up with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

After the division, we end up with 21177.591611 and a remainder of 4.34e-05.
