We divide 42572177 by 306
The aim is to understand the frequency of 306 in 42572177.

On to step 1:
306 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 306

Moving on to step 2:
42 divided by 306 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 306

Step 3:
425 divided by 306 is 1 with a remainder of 119.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 306 from 425 to get 119.
Take the next digit (7) from the dividend and append it to 119, then repeat: 1197 / 306

Let's proceed to step 4:
306 goes into 1197 3 times with a remainder of 279.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 918 from 1197 to get 279.
Take the next digit (2) from the dividend and append it to 279, then repeat: 2792 / 306

Moving on to step 5:
When dividing 2792 by 306, we get 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 139.0
If we take 2754 away from 2792, we end up with 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 306

On to step 6:
381 divided by 306 is 1 with a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 1391.0
The remainder is 75 after subtracting 306 from 381.
Fetch the next digit (7) from the dividend, attach it to 75 and continue: 757 / 306

Step 7:
757 divided by 306 is 2 with a remainder of 145.
Use 2 as the next digit of our solution. 
Result so far: 13912.0
The remainder is 145 after subtracting 612 from 757.
Take the next digit (7) from the dividend and append it to 145, then repeat: 1457 / 306

Step 8:
The number 306 fits into 1457 4 times, leaving a remainder of 233.
Write down 4 as next digit of the result. 
Result so far: 139124.0
If we take 1224 away from 1457, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 9:
When dividing 2330 by 306, we get 7 with a remainder of 188.
Put 7 as the next digit of the answer. 
Result so far: 139124.7
If we take 2142 away from 2330, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 10:
The number 306 fits into 1880 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 139124.76
If we subtract 1836 from 1880, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
440 divided by 306 is 1 with a remainder of 134.
The next digit of our result is 1. 
Result so far: 139124.761
Subtracting 306 from 440 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 12:
If we divide 1340 by 306, we get 4 and a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 139124.7614
Deduct 1224 from 1340 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 13:
If we divide 1160 by 306, we get 3 and a remainder of 242.
Use 3 as the next digit of our solution. 
Result so far: 139124.76143
Subtracting 918 from 1160 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 14:
The number 306 fits into 2420 7 times, leaving a remainder of 278.
Use 7 as the next digit of our solution. 
Result so far: 139124.761437
If we take 2142 away from 2420, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 15:
306 can be fit into 2780 9 times, resulting in a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 139124.7614379
If we subtract 2754 from 2780, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 16:
If we divide 260 by 306, we get 0 and a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 139124.7614379
Subtract 0 from 260 to get 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 result is 139124.7614379 with a remainder of 2.6e-07.
