38070107 divided by 438 
The aim is to understand the frequency of 438 in 38070107.

Moving on to step 1:
When dividing 3 by 438, 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.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 438

Going ahead to step 2:
If we divide 38 by 438, we get 0 and a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 438

Moving on to step 3:
If we divide 380 by 438, we get 0 and a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 380, we end up with 380.
Bring next digit (7) of the dividend behind the 380 and repeat the process: 3807 / 438

Step 4:
When dividing 3807 by 438, we get 8 with a remainder of 303.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 3504 from 3807 leaves us with 303.
Append the next digit (0) from the dividend to 303 and continue with: 3030 / 438

Advancing to step 5:
438 can be fit into 3030 6 times, resulting in a remainder of 402.
Write down 6 as next digit of the result. 
Result so far: 86.0
The remainder is 402 after subtracting 2628 from 3030.
Fetch the next digit (1) from the dividend, attach it to 402 and continue: 4021 / 438

On to step 6:
4021 divided by 438 is 9 with a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 869.0
Subtract 3942 from 4021 to get 79.
Append the next digit (0) from the dividend to 79 and continue with: 790 / 438

Moving on to step 7:
If we divide 790 by 438, we get 1 and a remainder of 352.
Put 1 as the next digit of the answer. 
Result so far: 8691.0
If we take 438 away from 790, we end up with 352.
Grab the next digit (7) from the dividend, add it to 352, then carry on: 3527 / 438

Moving on to step 8:
The number 438 fits into 3527 8 times, leaving a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 86918.0
Deduct 3504 from 3527 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
230 divided by 438 is 0 with a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 86918.0
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 10:
When dividing 2300 by 438, we get 5 with a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 86918.05
If we take 2190 away from 2300, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 11:
When dividing 1100 by 438, we get 2 with a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 86918.052
The remainder is 224 after subtracting 876 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 12:
2240 divided by 438 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 86918.0525
Subtract 2190 from 2240 to 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.

Let's proceed to step 13:
The number 438 fits into 500 1 times, leaving a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 86918.05251
The remainder is 62 after subtracting 438 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
438 goes into 620 1 times with a remainder of 182.
Put 1 as the next digit of the answer. 
Result so far: 86918.052511
Subtracting 438 from 620 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The quotient of the division is 86918.052511, and the remainder is 1.82e-05.
