We look at the division of 49614710 by 387 
The aim is to understand the frequency of 387 in 49614710.

Advancing to step 1:
387 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 387

Advancing to step 2:
49 divided by 387 is 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Take the next digit (6) from the dividend and append it to 49, then repeat: 496 / 387

Advancing to step 3:
If we divide 496 by 387, we get 1 and a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 387 away from 496, we end up with 109.
Include the next digit (1) from the dividend after 109, then repeat: 1091 / 387

Moving on to step 4:
1091 divided by 387 is 2 with a remainder of 317.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 774 away from 1091, we end up with 317.
Append the next digit (4) from the dividend to 317 and continue with: 3174 / 387

Advancing to step 5:
387 goes into 3174 8 times with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 128.0
If we subtract 3096 from 3174, we get 78.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 387

On to step 6:
787 divided by 387 is 2 with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 1282.0
The remainder is 13 after subtracting 774 from 787.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 387

On to step 7:
The number 387 fits into 131 0 times, leaving a remainder of 131.
Record the quotient 0 as the next digit in the result. 
Result so far: 12820.0
Subtracting 0 from 131 leaves us with 131.
Append the next digit (0) from the dividend to 131 and continue with: 1310 / 387

Going ahead to step 8:
If we divide 1310 by 387, we get 3 and a remainder of 149.
The next digit of our result is 3. 
Result so far: 128203.0
Subtracting 1161 from 1310 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 9:
387 goes into 1490 3 times with a remainder of 329.
Put 3 as the next digit of the answer. 
Result so far: 128203.3
Subtracting 1161 from 1490 leaves us with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Advancing to step 10:
When dividing 3290 by 387, we get 8 with a remainder of 194.
Record the quotient 8 as the next digit in the result. 
Result so far: 128203.38
If we subtract 3096 from 3290, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 11:
387 goes into 1940 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 128203.385
If we subtract 1935 from 1940, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
The number 387 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 128203.385
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
When dividing 500 by 387, we get 1 with a remainder of 113.
Use 1 as the next digit of our solution. 
Result so far: 128203.38501
Subtracting 387 from 500 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 14:
387 can be fit into 1130 2 times, resulting in a remainder of 356.
Record the quotient 2 as the next digit in the result. 
Result so far: 128203.385012
Subtracting 774 from 1130 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 15:
387 can be fit into 3560 9 times, resulting in a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 128203.3850129
Subtract 3483 from 3560 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 16:
387 goes into 770 1 times with a remainder of 383.
Write down 1 as next digit of the result. 
Result so far: 128203.38501291
Subtract 387 from 770 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

The final outcome is 128203.38501291, with a leftover of 3.83e-07.
