7987703 divided by 557 
The aim is to understand the frequency of 557 in 7987703.

On to step 1:
When dividing 7 by 557, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 557

Let's proceed to step 2:
When dividing 79 by 557, we get 0 with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 557

Going ahead to step 3:
If we divide 798 by 557, we get 1 and a remainder of 241.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 557 from 798, we get 241.
Take the next digit (7) from the dividend and append it to 241, then repeat: 2417 / 557

On to step 4:
When dividing 2417 by 557, we get 4 with a remainder of 189.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 2228 from 2417 to get 189.
Fetch the next digit (7) from the dividend, attach it to 189 and continue: 1897 / 557

Let's proceed to step 5:
When dividing 1897 by 557, we get 3 with a remainder of 226.
Write down 3 as next digit of the result. 
Result so far: 143.0
Deduct 1671 from 1897 and we're left with 226.
Include the next digit (0) from the dividend after 226, then repeat: 2260 / 557

Step 6:
557 goes into 2260 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 1434.0
If we subtract 2228 from 2260, we get 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 557

Advancing to step 7:
The number 557 fits into 323 0 times, leaving a remainder of 323.
Put 0 as the next digit of the answer. 
Result so far: 14340.0
Subtracting 0 from 323 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Going ahead to step 8:
3230 divided by 557 is 5 with a remainder of 445.
Write down 5 as next digit of the result. 
Result so far: 14340.5
Subtracting 2785 from 3230 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 9:
If we divide 4450 by 557, we get 7 and a remainder of 551.
The number 7 becomes the next digit in our result. 
Result so far: 14340.57
The remainder is 551 after subtracting 3899 from 4450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Step 10:
557 goes into 5510 9 times with a remainder of 497.
The next digit of our result is 9. 
Result so far: 14340.579
Subtract 5013 from 5510 to get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Let's proceed to step 11:
557 can be fit into 4970 8 times, resulting in a remainder of 514.
Write down 8 as next digit of the result. 
Result so far: 14340.5798
If we subtract 4456 from 4970, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Going ahead to step 12:
557 goes into 5140 9 times with a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 14340.57989
Subtracting 5013 from 5140 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 13:
557 goes into 1270 2 times with a remainder of 156.
The number 2 becomes the next digit in our result. 
Result so far: 14340.579892
If we subtract 1114 from 1270, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 14:
557 can be fit into 1560 2 times, resulting in a remainder of 446.
Use 2 as the next digit of our solution. 
Result so far: 14340.5798922
The remainder is 446 after subtracting 1114 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

The final result is 14340.5798922 with a remainder of 4.46e-06.
