We're dividing 11611431 by 553 
The aim is to understand the frequency of 553 in 11611431.

Going ahead to step 1:
553 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 553

Moving on to step 2:
The number 553 fits into 11 0 times, leaving a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 553

Going ahead to step 3:
If we divide 116 by 553, we get 0 and a remainder of 116.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 116 to get 116.
Append the next digit (1) from the dividend to 116 and continue with: 1161 / 553

Step 4:
553 goes into 1161 2 times with a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1106 away from 1161, we end up with 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 553

Going ahead to step 5:
If we divide 551 by 553, we get 0 and a remainder of 551.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 551 leaves us with 551.
Bring next digit (4) of the dividend behind the 551 and repeat the process: 5514 / 553

Going ahead to step 6:
If we divide 5514 by 553, we get 9 and a remainder of 537.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
Subtracting 4977 from 5514 leaves us with 537.
Take the next digit (3) from the dividend and append it to 537, then repeat: 5373 / 553

On to step 7:
When dividing 5373 by 553, we get 9 with a remainder of 396.
Put 9 as the next digit of the answer. 
Result so far: 2099.0
Subtracting 4977 from 5373 leaves us with 396.
Append the next digit (1) from the dividend to 396 and continue with: 3961 / 553

Advancing to step 8:
If we divide 3961 by 553, we get 7 and a remainder of 90.
The next digit of our result is 7. 
Result so far: 20997.0
Deduct 3871 from 3961 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 9:
The number 553 fits into 900 1 times, leaving a remainder of 347.
Write down 1 as next digit of the result. 
Result so far: 20997.1
If we take 553 away from 900, we end up with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Advancing to step 10:
553 goes into 3470 6 times with a remainder of 152.
Record the quotient 6 as the next digit in the result. 
Result so far: 20997.16
Deduct 3318 from 3470 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 11:
When dividing 1520 by 553, we get 2 with a remainder of 414.
The number 2 becomes the next digit in our result. 
Result so far: 20997.162
If we subtract 1106 from 1520, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 12:
4140 divided by 553 is 7 with a remainder of 269.
Record the quotient 7 as the next digit in the result. 
Result so far: 20997.1627
Subtracting 3871 from 4140 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 13:
When dividing 2690 by 553, we get 4 with a remainder of 478.
The next digit of our result is 4. 
Result so far: 20997.16274
Deduct 2212 from 2690 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 14:
4780 divided by 553 is 8 with a remainder of 356.
The next digit of our result is 8. 
Result so far: 20997.162748
Deduct 4424 from 4780 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 15:
3560 divided by 553 is 6 with a remainder of 242.
Record the quotient 6 as the next digit in the result. 
Result so far: 20997.1627486
Subtracting 3318 from 3560 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 16:
553 can be fit into 2420 4 times, resulting in a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 20997.16274864
Subtracting 2212 from 2420 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Our division results in 20997.16274864 with a remaining 2.08e-07.
