We look at the division of 3546389 by 606 
The aim is to understand the frequency of 606 in 3546389.

Advancing to step 1:
3 divided by 606 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 606

Let's proceed to step 2:
When dividing 35 by 606, we get 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 606

On to step 3:
If we divide 354 by 606, we get 0 and a remainder of 354.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 354 leaves us with 354.
Fetch the next digit (6) from the dividend, attach it to 354 and continue: 3546 / 606

Advancing to step 4:
3546 divided by 606 is 5 with a remainder of 516.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 3030 from 3546 leaves us with 516.
Bring next digit (3) of the dividend behind the 516 and repeat the process: 5163 / 606

Going ahead to step 5:
When dividing 5163 by 606, we get 8 with a remainder of 315.
Put 8 as the next digit of the answer. 
Result so far: 58.0
Subtract 4848 from 5163 to get 315.
Append the next digit (8) from the dividend to 315 and continue with: 3158 / 606

Going ahead to step 6:
If we divide 3158 by 606, we get 5 and a remainder of 128.
Use 5 as the next digit of our solution. 
Result so far: 585.0
If we subtract 3030 from 3158, we get 128.
Take the next digit (9) from the dividend and append it to 128, then repeat: 1289 / 606

Moving on to step 7:
When dividing 1289 by 606, we get 2 with a remainder of 77.
Use 2 as the next digit of our solution. 
Result so far: 5852.0
If we take 1212 away from 1289, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 8:
The number 606 fits into 770 1 times, leaving a remainder of 164.
Record the quotient 1 as the next digit in the result. 
Result so far: 5852.1
If we subtract 606 from 770, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 9:
The number 606 fits into 1640 2 times, leaving a remainder of 428.
Record the quotient 2 as the next digit in the result. 
Result so far: 5852.12
If we subtract 1212 from 1640, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 10:
4280 divided by 606 is 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 5852.127
If we subtract 4242 from 4280, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
606 goes into 380 0 times with a remainder of 380.
The next digit of our result is 0. 
Result so far: 5852.127
If we subtract 0 from 380, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 12:
3800 divided by 606 is 6 with a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 5852.12706
Deduct 3636 from 3800 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 13:
606 goes into 1640 2 times with a remainder of 428.
The number 2 becomes the next digit in our result. 
Result so far: 5852.127062
If we subtract 1212 from 1640, we get 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 14:
606 goes into 4280 7 times with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 5852.1270627
Subtract 4242 from 4280 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 15:
The number 606 fits into 380 0 times, leaving a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 5852.1270627
If we take 0 away from 380, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final outcome is 5852.1270627, with a leftover of 3.8e-07.
