We look at the division of 83776343 by 554 
The aim is to understand the frequency of 554 in 83776343.

Step 1:
The number 554 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 554

Advancing to step 2:
The number 554 fits into 83 0 times, leaving a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 554

Going ahead to step 3:
If we divide 837 by 554, we get 1 and a remainder of 283.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 554 away from 837, we end up with 283.
Grab the next digit (7) from the dividend, add it to 283, then carry on: 2837 / 554

Going ahead to step 4:
554 can be fit into 2837 5 times, resulting in a remainder of 67.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 2770 from 2837 leaves us with 67.
Take the next digit (6) from the dividend and append it to 67, then repeat: 676 / 554

Going ahead to step 5:
When dividing 676 by 554, we get 1 with a remainder of 122.
The next digit of our result is 1. 
Result so far: 151.0
The remainder is 122 after subtracting 554 from 676.
Append the next digit (3) from the dividend to 122 and continue with: 1223 / 554

Advancing to step 6:
When dividing 1223 by 554, we get 2 with a remainder of 115.
The number 2 becomes the next digit in our result. 
Result so far: 1512.0
If we subtract 1108 from 1223, we get 115.
Fetch the next digit (4) from the dividend, attach it to 115 and continue: 1154 / 554

Let's proceed to step 7:
The number 554 fits into 1154 2 times, leaving a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 15122.0
Deduct 1108 from 1154 and we're left with 46.
Fetch the next digit (3) from the dividend, attach it to 46 and continue: 463 / 554

Going ahead to step 8:
When dividing 463 by 554, we get 0 with a remainder of 463.
The number 0 becomes the next digit in our result. 
Result so far: 151220.0
If we take 0 away from 463, we end up with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Advancing to step 9:
The number 554 fits into 4630 8 times, leaving a remainder of 198.
Put 8 as the next digit of the answer. 
Result so far: 151220.8
Subtracting 4432 from 4630 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 10:
When dividing 1980 by 554, we get 3 with a remainder of 318.
Put 3 as the next digit of the answer. 
Result so far: 151220.83
If we take 1662 away from 1980, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 11:
If we divide 3180 by 554, we get 5 and a remainder of 410.
Put 5 as the next digit of the answer. 
Result so far: 151220.835
Subtract 2770 from 3180 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 12:
554 goes into 4100 7 times with a remainder of 222.
Record the quotient 7 as the next digit in the result. 
Result so far: 151220.8357
If we subtract 3878 from 4100, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 13:
554 goes into 2220 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 151220.83574
Deduct 2216 from 2220 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
The number 554 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 151220.83574
Subtracting 0 from 40 leaves us 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.

Let's proceed to step 15:
The number 554 fits into 400 0 times, leaving a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 151220.83574
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 151220.83574 and a remainder of 4e-06.
