38083221 ÷ 615 
The aim is to understand the frequency of 615 in 38083221.

Step 1:
When dividing 3 by 615, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 615

Moving on to step 2:
615 can be fit into 38 0 times, resulting in a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 615

Going ahead to step 3:
380 divided by 615 is 0 with a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 380 after subtracting 0 from 380.
Fetch the next digit (8) from the dividend, attach it to 380 and continue: 3808 / 615

Let's proceed to step 4:
The number 615 fits into 3808 6 times, leaving a remainder of 118.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 3690 from 3808 leaves us with 118.
Fetch the next digit (3) from the dividend, attach it to 118 and continue: 1183 / 615

On to step 5:
The number 615 fits into 1183 1 times, leaving a remainder of 568.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we take 615 away from 1183, we end up with 568.
Include the next digit (2) from the dividend after 568, then repeat: 5682 / 615

Going ahead to step 6:
5682 divided by 615 is 9 with a remainder of 147.
Use 9 as the next digit of our solution. 
Result so far: 619.0
If we subtract 5535 from 5682, we get 147.
Append the next digit (2) from the dividend to 147 and continue with: 1472 / 615

Advancing to step 7:
If we divide 1472 by 615, we get 2 and a remainder of 242.
Record the quotient 2 as the next digit in the result. 
Result so far: 6192.0
Subtract 1230 from 1472 to get 242.
Grab the next digit (1) from the dividend, add it to 242, then carry on: 2421 / 615

Advancing to step 8:
If we divide 2421 by 615, we get 3 and a remainder of 576.
Record the quotient 3 as the next digit in the result. 
Result so far: 61923.0
If we subtract 1845 from 2421, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 9:
If we divide 5760 by 615, we get 9 and a remainder of 225.
Use 9 as the next digit of our solution. 
Result so far: 61923.9
Subtracting 5535 from 5760 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 10:
The number 615 fits into 2250 3 times, leaving a remainder of 405.
Write down 3 as next digit of the result. 
Result so far: 61923.93
Subtracting 1845 from 2250 leaves us with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 11:
If we divide 4050 by 615, we get 6 and a remainder of 360.
The number 6 becomes the next digit in our result. 
Result so far: 61923.936
Deduct 3690 from 4050 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 12:
If we divide 3600 by 615, we get 5 and a remainder of 525.
The next digit of our result is 5. 
Result so far: 61923.9365
If we take 3075 away from 3600, we end up with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Step 13:
The number 615 fits into 5250 8 times, leaving a remainder of 330.
The next digit of our result is 8. 
Result so far: 61923.93658
Deduct 4920 from 5250 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 14:
3300 divided by 615 is 5 with a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 61923.936585
Subtract 3075 from 3300 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 15:
If we divide 2250 by 615, we get 3 and a remainder of 405.
Put 3 as the next digit of the answer. 
Result so far: 61923.9365853
Subtract 1845 from 2250 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 16:
When dividing 4050 by 615, we get 6 with a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 61923.93658536
Deduct 3690 from 4050 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

In conclusion, the division gives 61923.93658536 with a balance of 3.6e-07.
