We're dividing 76703153 by 553 
The aim is to understand the frequency of 553 in 76703153.

Let's proceed to step 1:
7 divided by 553 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 553

Moving on to step 2:
76 divided by 553 is 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Fetch the next digit (7) from the dividend, attach it to 76 and continue: 767 / 553

Advancing to step 3:
The number 553 fits into 767 1 times, leaving a remainder of 214.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 553 from 767 leaves us with 214.
Include the next digit (0) from the dividend after 214, then repeat: 2140 / 553

On to step 4:
553 goes into 2140 3 times with a remainder of 481.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 1659 from 2140, we get 481.
Include the next digit (3) from the dividend after 481, then repeat: 4813 / 553

Advancing to step 5:
4813 divided by 553 is 8 with a remainder of 389.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we take 4424 away from 4813, we end up with 389.
Append the next digit (1) from the dividend to 389 and continue with: 3891 / 553

Going ahead to step 6:
If we divide 3891 by 553, we get 7 and a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 1387.0
If we take 3871 away from 3891, we end up with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 553

Step 7:
If we divide 205 by 553, we get 0 and a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 13870.0
If we take 0 away from 205, we end up with 205.
Include the next digit (3) from the dividend after 205, then repeat: 2053 / 553

Step 8:
553 goes into 2053 3 times with a remainder of 394.
Use 3 as the next digit of our solution. 
Result so far: 138703.0
The remainder is 394 after subtracting 1659 from 2053.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 9:
553 can be fit into 3940 7 times, resulting in a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 138703.7
Deduct 3871 from 3940 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 10:
If we divide 690 by 553, we get 1 and a remainder of 137.
Write down 1 as next digit of the result. 
Result so far: 138703.71
If we take 553 away from 690, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 11:
If we divide 1370 by 553, we get 2 and a remainder of 264.
The number 2 becomes the next digit in our result. 
Result so far: 138703.712
Subtracting 1106 from 1370 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 12:
If we divide 2640 by 553, we get 4 and a remainder of 428.
The number 4 becomes the next digit in our result. 
Result so far: 138703.7124
Subtracting 2212 from 2640 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 13:
If we divide 4280 by 553, we get 7 and a remainder of 409.
Write down 7 as next digit of the result. 
Result so far: 138703.71247
If we take 3871 away from 4280, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Let's proceed to step 14:
4090 divided by 553 is 7 with a remainder of 219.
Put 7 as the next digit of the answer. 
Result so far: 138703.712477
Deduct 3871 from 4090 and we're left with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

The final result is 138703.712477 with a remainder of 2.19e-05.
