48691389 ÷ 581 
The aim is to understand the frequency of 581 in 48691389.

Moving on 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
If we subtract 0 from 4, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 581

Let's proceed to step 2:
48 divided by 581 is 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 581

Advancing to step 3:
486 divided by 581 is 0 with a remainder of 486.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 486 and we're left with 486.
Append the next digit (9) from the dividend to 486 and continue with: 4869 / 581

Advancing to step 4:
4869 divided by 581 is 8 with a remainder of 221.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 4648 from 4869 to get 221.
Bring next digit (1) of the dividend behind the 221 and repeat the process: 2211 / 581

Advancing to step 5:
2211 divided by 581 is 3 with a remainder of 468.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we subtract 1743 from 2211, we get 468.
Take the next digit (3) from the dividend and append it to 468, then repeat: 4683 / 581

Let's proceed to step 6:
The number 581 fits into 4683 8 times, leaving a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 838.0
Deduct 4648 from 4683 and we're left with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 581

Advancing to step 7:
When dividing 358 by 581, we get 0 with a remainder of 358.
The number 0 becomes the next digit in our result. 
Result so far: 8380.0
Subtract 0 from 358 to get 358.
Append the next digit (9) from the dividend to 358 and continue with: 3589 / 581

Step 8:
When dividing 3589 by 581, we get 6 with a remainder of 103.
The number 6 becomes the next digit in our result. 
Result so far: 83806.0
If we subtract 3486 from 3589, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 9:
The number 581 fits into 1030 1 times, leaving a remainder of 449.
Write down 1 as next digit of the result. 
Result so far: 83806.1
The remainder is 449 after subtracting 581 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Advancing to step 10:
When dividing 4490 by 581, we get 7 with a remainder of 423.
Use 7 as the next digit of our solution. 
Result so far: 83806.17
Subtract 4067 from 4490 to get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Let's proceed to step 11:
If we divide 4230 by 581, we get 7 and a remainder of 163.
Use 7 as the next digit of our solution. 
Result so far: 83806.177
If we subtract 4067 from 4230, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

The quotient of the division is 83806.177, and the remainder is 0.0163.
