837369 ÷ 555 
The aim is to understand the frequency of 555 in 837369.

Going ahead to step 1:
555 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 555

On to step 2:
When dividing 83 by 555, we get 0 with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Fetch the next digit (7) from the dividend, attach it to 83 and continue: 837 / 555

On to step 3:
If we divide 837 by 555, we get 1 and a remainder of 282.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 555 from 837 to get 282.
Grab the next digit (3) from the dividend, add it to 282, then carry on: 2823 / 555

On to step 4:
If we divide 2823 by 555, we get 5 and a remainder of 48.
The next digit of our result is 5. 
Result so far: 15.0
If we take 2775 away from 2823, we end up with 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 555

Let's proceed to step 5:
555 goes into 486 0 times with a remainder of 486.
The next digit of our result is 0. 
Result so far: 150.0
If we take 0 away from 486, we end up with 486.
Append the next digit (9) from the dividend to 486 and continue with: 4869 / 555

Step 6:
555 goes into 4869 8 times with a remainder of 429.
The next digit of our result is 8. 
Result so far: 1508.0
If we take 4440 away from 4869, we end up with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

On to step 7:
The number 555 fits into 4290 7 times, leaving a remainder of 405.
The next digit of our result is 7. 
Result so far: 1508.7
Deduct 3885 from 4290 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 8:
4050 divided by 555 is 7 with a remainder of 165.
Record the quotient 7 as the next digit in the result. 
Result so far: 1508.77
Subtracting 3885 from 4050 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The quotient of the division is 1508.77, and the remainder is 0.165.
