We look at the division of 70147903 by 387 
The aim is to understand the frequency of 387 in 70147903.

Advancing to step 1:
387 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 387

Going ahead to step 2:
If we divide 70 by 387, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Fetch the next digit (1) from the dividend, attach it to 70 and continue: 701 / 387

Step 3:
701 divided by 387 is 1 with a remainder of 314.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 314 after subtracting 387 from 701.
Fetch the next digit (4) from the dividend, attach it to 314 and continue: 3144 / 387

Going ahead to step 4:
387 goes into 3144 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 3096 from 3144 leaves us with 48.
Fetch the next digit (7) from the dividend, attach it to 48 and continue: 487 / 387

On to step 5:
If we divide 487 by 387, we get 1 and a remainder of 100.
Use 1 as the next digit of our solution. 
Result so far: 181.0
Subtracting 387 from 487 leaves us with 100.
Bring next digit (9) of the dividend behind the 100 and repeat the process: 1009 / 387

Moving on to step 6:
1009 divided by 387 is 2 with a remainder of 235.
Write down 2 as next digit of the result. 
Result so far: 1812.0
Subtract 774 from 1009 to get 235.
Include the next digit (0) from the dividend after 235, then repeat: 2350 / 387

Let's proceed to step 7:
387 goes into 2350 6 times with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 18126.0
Subtracting 2322 from 2350 leaves us with 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 387

Step 8:
The number 387 fits into 283 0 times, leaving a remainder of 283.
The number 0 becomes the next digit in our result. 
Result so far: 181260.0
The remainder is 283 after subtracting 0 from 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Moving on to step 9:
The number 387 fits into 2830 7 times, leaving a remainder of 121.
Write down 7 as next digit of the result. 
Result so far: 181260.7
Deduct 2709 from 2830 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 10:
387 goes into 1210 3 times with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 181260.73
Deduct 1161 from 1210 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 11:
The number 387 fits into 490 1 times, leaving a remainder of 103.
Write down 1 as next digit of the result. 
Result so far: 181260.731
The remainder is 103 after subtracting 387 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 12:
1030 divided by 387 is 2 with a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 181260.7312
Subtracting 774 from 1030 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 13:
387 goes into 2560 6 times with a remainder of 238.
Use 6 as the next digit of our solution. 
Result so far: 181260.73126
Deduct 2322 from 2560 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 14:
387 can be fit into 2380 6 times, resulting in a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 181260.731266
If we subtract 2322 from 2380, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

In conclusion, the division gives 181260.731266 with a balance of 5.8e-06.
