Let's divide 40507538 by 581
The aim is to understand the frequency of 581 in 40507538.

Let's proceed to step 1:
4 divided by 581 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 581

Moving on to step 2:
40 divided by 581 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 581

Advancing to step 3:
405 divided by 581 is 0 with a remainder of 405.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 405, we get 405.
Append the next digit (0) from the dividend to 405 and continue with: 4050 / 581

Going ahead to step 4:
4050 divided by 581 is 6 with a remainder of 564.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 3486 from 4050 and we're left with 564.
Bring next digit (7) of the dividend behind the 564 and repeat the process: 5647 / 581

Let's proceed to step 5:
When dividing 5647 by 581, we get 9 with a remainder of 418.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we take 5229 away from 5647, we end up with 418.
Append the next digit (5) from the dividend to 418 and continue with: 4185 / 581

Let's proceed to step 6:
When dividing 4185 by 581, we get 7 with a remainder of 118.
The next digit of our result is 7. 
Result so far: 697.0
Subtract 4067 from 4185 to get 118.
Take the next digit (3) from the dividend and append it to 118, then repeat: 1183 / 581

Step 7:
The number 581 fits into 1183 2 times, leaving a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 6972.0
Subtracting 1162 from 1183 leaves us with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 581

Moving on to step 8:
If we divide 218 by 581, we get 0 and a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 69720.0
If we take 0 away from 218, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 9:
The number 581 fits into 2180 3 times, leaving a remainder of 437.
The next digit of our result is 3. 
Result so far: 69720.3
Subtract 1743 from 2180 to get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Moving on to step 10:
581 can be fit into 4370 7 times, resulting in a remainder of 303.
Record the quotient 7 as the next digit in the result. 
Result so far: 69720.37
Deduct 4067 from 4370 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Let's proceed to step 11:
581 goes into 3030 5 times with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 69720.375
Subtract 2905 from 3030 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 12:
1250 divided by 581 is 2 with a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 69720.3752
The remainder is 88 after subtracting 1162 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 13:
581 goes into 880 1 times with a remainder of 299.
Use 1 as the next digit of our solution. 
Result so far: 69720.37521
The remainder is 299 after subtracting 581 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Step 14:
2990 divided by 581 is 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 69720.375215
Subtracting 2905 from 2990 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 15:
581 goes into 850 1 times with a remainder of 269.
Record the quotient 1 as the next digit in the result. 
Result so far: 69720.3752151
If we take 581 away from 850, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 16:
When dividing 2690 by 581, we get 4 with a remainder of 366.
Record the quotient 4 as the next digit in the result. 
Result so far: 69720.37521514
Deduct 2324 from 2690 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

In conclusion, the division gives 69720.37521514 with a balance of 3.66e-07.
