Let's divide 37869994 by 357
The aim is to understand the frequency of 357 in 37869994.

Advancing to step 1:
When dividing 3 by 357, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 357

Step 2:
The number 357 fits into 37 0 times, leaving a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 357

On to step 3:
357 can be fit into 378 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 21 after subtracting 357 from 378.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 357

Going ahead to step 4:
357 goes into 216 0 times with a remainder of 216.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 216 leaves us with 216.
Include the next digit (9) from the dividend after 216, then repeat: 2169 / 357

Advancing to step 5:
If we divide 2169 by 357, we get 6 and a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 106.0
If we take 2142 away from 2169, we end up with 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 357

Let's proceed to step 6:
357 goes into 279 0 times with a remainder of 279.
The next digit of our result is 0. 
Result so far: 1060.0
If we take 0 away from 279, we end up with 279.
Grab the next digit (9) from the dividend, add it to 279, then carry on: 2799 / 357

Step 7:
357 can be fit into 2799 7 times, resulting in a remainder of 300.
The number 7 becomes the next digit in our result. 
Result so far: 10607.0
Subtract 2499 from 2799 to get 300.
Fetch the next digit (4) from the dividend, attach it to 300 and continue: 3004 / 357

Advancing to step 8:
3004 divided by 357 is 8 with a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 106078.0
If we subtract 2856 from 3004, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 9:
If we divide 1480 by 357, we get 4 and a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 106078.4
Subtracting 1428 from 1480 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
When dividing 520 by 357, we get 1 with a remainder of 163.
Put 1 as the next digit of the answer. 
Result so far: 106078.41
Subtracting 357 from 520 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 11:
357 can be fit into 1630 4 times, resulting in a remainder of 202.
Write down 4 as next digit of the result. 
Result so far: 106078.414
If we take 1428 away from 1630, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 12:
2020 divided by 357 is 5 with a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 106078.4145
The remainder is 235 after subtracting 1785 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 13:
2350 divided by 357 is 6 with a remainder of 208.
Record the quotient 6 as the next digit in the result. 
Result so far: 106078.41456
Subtract 2142 from 2350 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 14:
357 goes into 2080 5 times with a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 106078.414565
Subtracting 1785 from 2080 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 15:
357 goes into 2950 8 times with a remainder of 94.
Put 8 as the next digit of the answer. 
Result so far: 106078.4145658
Deduct 2856 from 2950 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 16:
If we divide 940 by 357, we get 2 and a remainder of 226.
The number 2 becomes the next digit in our result. 
Result so far: 106078.41456582
The remainder is 226 after subtracting 714 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Our division results in 106078.41456582 with a remaining 2.26e-07.
