38783858 divided by 907 
The aim is to understand the frequency of 907 in 38783858.

On to step 1:
The number 907 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 907

On to step 2:
When dividing 38 by 907, we get 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 907

Step 3:
When dividing 387 by 907, we get 0 with a remainder of 387.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 387, we end up with 387.
Bring next digit (8) of the dividend behind the 387 and repeat the process: 3878 / 907

Going ahead to step 4:
907 goes into 3878 4 times with a remainder of 250.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 3628 from 3878 to get 250.
Grab the next digit (3) from the dividend, add it to 250, then carry on: 2503 / 907

Moving on to step 5:
If we divide 2503 by 907, we get 2 and a remainder of 689.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 1814 from 2503 to get 689.
Take the next digit (8) from the dividend and append it to 689, then repeat: 6898 / 907

Moving on to step 6:
When dividing 6898 by 907, we get 7 with a remainder of 549.
Record the quotient 7 as the next digit in the result. 
Result so far: 427.0
If we subtract 6349 from 6898, we get 549.
Take the next digit (5) from the dividend and append it to 549, then repeat: 5495 / 907

On to step 7:
If we divide 5495 by 907, we get 6 and a remainder of 53.
The number 6 becomes the next digit in our result. 
Result so far: 4276.0
Subtract 5442 from 5495 to get 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 907

On to step 8:
The number 907 fits into 538 0 times, leaving a remainder of 538.
Write down 0 as next digit of the result. 
Result so far: 42760.0
If we take 0 away from 538, we end up with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

On to step 9:
5380 divided by 907 is 5 with a remainder of 845.
Record the quotient 5 as the next digit in the result. 
Result so far: 42760.5
If we subtract 4535 from 5380, we get 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

On to step 10:
The number 907 fits into 8450 9 times, leaving a remainder of 287.
The number 9 becomes the next digit in our result. 
Result so far: 42760.59
If we take 8163 away from 8450, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Let's proceed to step 11:
If we divide 2870 by 907, we get 3 and a remainder of 149.
Put 3 as the next digit of the answer. 
Result so far: 42760.593
If we take 2721 away from 2870, we end up 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.

Let's proceed to step 12:
907 goes into 1490 1 times with a remainder of 583.
Use 1 as the next digit of our solution. 
Result so far: 42760.5931
If we subtract 907 from 1490, we get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

On to step 13:
5830 divided by 907 is 6 with a remainder of 388.
Record the quotient 6 as the next digit in the result. 
Result so far: 42760.59316
If we subtract 5442 from 5830, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 14:
If we divide 3880 by 907, we get 4 and a remainder of 252.
Write down 4 as next digit of the result. 
Result so far: 42760.593164
If we subtract 3628 from 3880, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 15:
The number 907 fits into 2520 2 times, leaving a remainder of 706.
Use 2 as the next digit of our solution. 
Result so far: 42760.5931642
Deduct 1814 from 2520 and we're left with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

On to step 16:
7060 divided by 907 is 7 with a remainder of 711.
Write down 7 as next digit of the result. 
Result so far: 42760.59316427
Subtracting 6349 from 7060 leaves us with 711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

In conclusion, the division gives 42760.59316427 with a balance of 7.11e-07.
