We look at the division of 23600510 by 556 
The aim is to understand the frequency of 556 in 23600510.

Let's proceed to step 1:
When dividing 2 by 556, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 556

Step 2:
556 goes into 23 0 times with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 556

Going ahead to step 3:
The number 556 fits into 236 0 times, leaving a remainder of 236.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 236, we get 236.
Grab the next digit (0) from the dividend, add it to 236, then carry on: 2360 / 556

Moving on to step 4:
556 can be fit into 2360 4 times, resulting in a remainder of 136.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 136 after subtracting 2224 from 2360.
Include the next digit (0) from the dividend after 136, then repeat: 1360 / 556

Moving on to step 5:
If we divide 1360 by 556, we get 2 and a remainder of 248.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we subtract 1112 from 1360, we get 248.
Bring next digit (5) of the dividend behind the 248 and repeat the process: 2485 / 556

Advancing to step 6:
The number 556 fits into 2485 4 times, leaving a remainder of 261.
Use 4 as the next digit of our solution. 
Result so far: 424.0
Deduct 2224 from 2485 and we're left with 261.
Bring next digit (1) of the dividend behind the 261 and repeat the process: 2611 / 556

Going ahead to step 7:
The number 556 fits into 2611 4 times, leaving a remainder of 387.
Put 4 as the next digit of the answer. 
Result so far: 4244.0
If we take 2224 away from 2611, we end up with 387.
Append the next digit (0) from the dividend to 387 and continue with: 3870 / 556

Going ahead to step 8:
The number 556 fits into 3870 6 times, leaving a remainder of 534.
Use 6 as the next digit of our solution. 
Result so far: 42446.0
The remainder is 534 after subtracting 3336 from 3870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Advancing to step 9:
556 goes into 5340 9 times with a remainder of 336.
Use 9 as the next digit of our solution. 
Result so far: 42446.9
If we take 5004 away from 5340, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 10:
3360 divided by 556 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 42446.96
Deduct 3336 from 3360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
If we divide 240 by 556, we get 0 and a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 42446.96
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
The number 556 fits into 2400 4 times, leaving a remainder of 176.
The number 4 becomes the next digit in our result. 
Result so far: 42446.9604
Deduct 2224 from 2400 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 13:
When dividing 1760 by 556, we get 3 with a remainder of 92.
Use 3 as the next digit of our solution. 
Result so far: 42446.96043
If we subtract 1668 from 1760, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 14:
920 divided by 556 is 1 with a remainder of 364.
Record the quotient 1 as the next digit in the result. 
Result so far: 42446.960431
Subtracting 556 from 920 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 15:
The number 556 fits into 3640 6 times, leaving a remainder of 304.
Record the quotient 6 as the next digit in the result. 
Result so far: 42446.9604316
Subtract 3336 from 3640 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 16:
When dividing 3040 by 556, we get 5 with a remainder of 260.
The number 5 becomes the next digit in our result. 
Result so far: 42446.96043165
If we take 2780 away from 3040, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 42446.96043165, with a leftover of 2.6e-07.
