We're dividing 62160978 by 387 
The aim is to understand the frequency of 387 in 62160978.

Step 1:
The number 387 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 387

Step 2:
When dividing 62 by 387, we get 0 with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 387

Step 3:
387 can be fit into 621 1 times, resulting in a remainder of 234.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 387 from 621 and we're left with 234.
Include the next digit (6) from the dividend after 234, then repeat: 2346 / 387

On to step 4:
When dividing 2346 by 387, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 2322 from 2346 to get 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 387

Moving on to step 5:
The number 387 fits into 240 0 times, leaving a remainder of 240.
The next digit of our result is 0. 
Result so far: 160.0
If we take 0 away from 240, we end up with 240.
Include the next digit (9) from the dividend after 240, then repeat: 2409 / 387

Moving on to step 6:
2409 divided by 387 is 6 with a remainder of 87.
Write down 6 as next digit of the result. 
Result so far: 1606.0
The remainder is 87 after subtracting 2322 from 2409.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 387

Step 7:
The number 387 fits into 877 2 times, leaving a remainder of 103.
Record the quotient 2 as the next digit in the result. 
Result so far: 16062.0
The remainder is 103 after subtracting 774 from 877.
Grab the next digit (8) from the dividend, add it to 103, then carry on: 1038 / 387

Advancing to step 8:
If we divide 1038 by 387, we get 2 and a remainder of 264.
The number 2 becomes the next digit in our result. 
Result so far: 160622.0
The remainder is 264 after subtracting 774 from 1038.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 9:
When dividing 2640 by 387, we get 6 with a remainder of 318.
Use 6 as the next digit of our solution. 
Result so far: 160622.6
Deduct 2322 from 2640 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 10:
The number 387 fits into 3180 8 times, leaving a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 160622.68
Subtracting 3096 from 3180 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
If we divide 840 by 387, we get 2 and a remainder of 66.
The next digit of our result is 2. 
Result so far: 160622.682
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 12:
387 can be fit into 660 1 times, resulting in a remainder of 273.
Use 1 as the next digit of our solution. 
Result so far: 160622.6821
Subtract 387 from 660 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Moving on to step 13:
When dividing 2730 by 387, we get 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 160622.68217
If we subtract 2709 from 2730, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 14:
The number 387 fits into 210 0 times, leaving a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 160622.68217
Deduct 0 from 210 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 15:
If we divide 2100 by 387, we get 5 and a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 160622.6821705
Subtract 1935 from 2100 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 16:
When dividing 1650 by 387, we get 4 with a remainder of 102.
Use 4 as the next digit of our solution. 
Result so far: 160622.68217054
Subtract 1548 from 1650 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

After the division, we end up with 160622.68217054 and a remainder of 1.02e-07.
