37821219 divided by 387 
The aim is to understand the frequency of 387 in 37821219.

On to step 1:
387 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 387

Moving on to step 2:
387 can be fit into 37 0 times, resulting in a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 387

Step 3:
387 goes into 378 0 times with a remainder of 378.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 378, we get 378.
Append the next digit (2) from the dividend to 378 and continue with: 3782 / 387

On to step 4:
When dividing 3782 by 387, we get 9 with a remainder of 299.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 299 after subtracting 3483 from 3782.
Take the next digit (1) from the dividend and append it to 299, then repeat: 2991 / 387

Moving on to step 5:
When dividing 2991 by 387, we get 7 with a remainder of 282.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Subtracting 2709 from 2991 leaves us with 282.
Bring next digit (2) of the dividend behind the 282 and repeat the process: 2822 / 387

Going ahead to step 6:
If we divide 2822 by 387, we get 7 and a remainder of 113.
The number 7 becomes the next digit in our result. 
Result so far: 977.0
Subtracting 2709 from 2822 leaves us with 113.
Fetch the next digit (1) from the dividend, attach it to 113 and continue: 1131 / 387

Step 7:
The number 387 fits into 1131 2 times, leaving a remainder of 357.
Put 2 as the next digit of the answer. 
Result so far: 9772.0
If we take 774 away from 1131, we end up with 357.
Grab the next digit (9) from the dividend, add it to 357, then carry on: 3579 / 387

Step 8:
387 goes into 3579 9 times with a remainder of 96.
Record the quotient 9 as the next digit in the result. 
Result so far: 97729.0
Deduct 3483 from 3579 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
The number 387 fits into 960 2 times, leaving a remainder of 186.
Use 2 as the next digit of our solution. 
Result so far: 97729.2
If we take 774 away from 960, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 10:
1860 divided by 387 is 4 with a remainder of 312.
The next digit of our result is 4. 
Result so far: 97729.24
Subtract 1548 from 1860 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 11:
The number 387 fits into 3120 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 97729.248
The remainder is 24 after subtracting 3096 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
If we divide 240 by 387, we get 0 and a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 97729.248
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
2400 divided by 387 is 6 with a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 97729.24806
Subtracting 2322 from 2400 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 14:
387 goes into 780 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 97729.248062
The remainder is 6 after subtracting 774 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 15:
387 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 97729.248062
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 16:
When dividing 600 by 387, we get 1 with a remainder of 213.
The number 1 becomes the next digit in our result. 
Result so far: 97729.24806201
The remainder is 213 after subtracting 387 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

The final result is 97729.24806201 with a remainder of 2.13e-07.
