We divide 87072072 by 606
The aim is to understand the frequency of 606 in 87072072.

Going ahead to step 1:
When dividing 8 by 606, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 606

On to step 2:
If we divide 87 by 606, we get 0 and a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Fetch the next digit (0) from the dividend, attach it to 87 and continue: 870 / 606

Moving on to step 3:
870 divided by 606 is 1 with a remainder of 264.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 606 from 870 and we're left with 264.
Append the next digit (7) from the dividend to 264 and continue with: 2647 / 606

Moving on to step 4:
606 can be fit into 2647 4 times, resulting in a remainder of 223.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 2424 away from 2647, we end up with 223.
Bring next digit (2) of the dividend behind the 223 and repeat the process: 2232 / 606

Let's proceed to step 5:
When dividing 2232 by 606, we get 3 with a remainder of 414.
Put 3 as the next digit of the answer. 
Result so far: 143.0
If we subtract 1818 from 2232, we get 414.
Append the next digit (0) from the dividend to 414 and continue with: 4140 / 606

Advancing to step 6:
When dividing 4140 by 606, we get 6 with a remainder of 504.
Write down 6 as next digit of the result. 
Result so far: 1436.0
Deduct 3636 from 4140 and we're left with 504.
Bring next digit (7) of the dividend behind the 504 and repeat the process: 5047 / 606

Going ahead to step 7:
606 goes into 5047 8 times with a remainder of 199.
The number 8 becomes the next digit in our result. 
Result so far: 14368.0
If we take 4848 away from 5047, we end up with 199.
Bring next digit (2) of the dividend behind the 199 and repeat the process: 1992 / 606

Moving on to step 8:
If we divide 1992 by 606, we get 3 and a remainder of 174.
The next digit of our result is 3. 
Result so far: 143683.0
The remainder is 174 after subtracting 1818 from 1992.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 9:
1740 divided by 606 is 2 with a remainder of 528.
Record the quotient 2 as the next digit in the result. 
Result so far: 143683.2
If we take 1212 away from 1740, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 10:
When dividing 5280 by 606, we get 8 with a remainder of 432.
Use 8 as the next digit of our solution. 
Result so far: 143683.28
Subtract 4848 from 5280 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 11:
606 goes into 4320 7 times with a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 143683.287
Subtracting 4242 from 4320 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 12:
606 can be fit into 780 1 times, resulting in a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 143683.2871
Subtract 606 from 780 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 13:
606 can be fit into 1740 2 times, resulting in a remainder of 528.
Record the quotient 2 as the next digit in the result. 
Result so far: 143683.28712
Subtracting 1212 from 1740 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 14:
The number 606 fits into 5280 8 times, leaving a remainder of 432.
Put 8 as the next digit of the answer. 
Result so far: 143683.287128
Subtract 4848 from 5280 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 15:
If we divide 4320 by 606, we get 7 and a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 143683.2871287
Subtracting 4242 from 4320 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 16:
The number 606 fits into 780 1 times, leaving a remainder of 174.
Put 1 as the next digit of the answer. 
Result so far: 143683.28712871
Deduct 606 from 780 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

The final result is 143683.28712871 with a remainder of 1.74e-07.
