We look at the division of 8117849 by 581 
We want to figure out the number of times 8117849 can be divided by 581.

On to step 1:
When dividing 8 by 581, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 581

On to step 2:
When dividing 81 by 581, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (1) from the dividend to 81 and continue with: 811 / 581

On to step 3:
811 divided by 581 is 1 with a remainder of 230.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 581 from 811 and we're left with 230.
Append the next digit (7) from the dividend to 230 and continue with: 2307 / 581

Step 4:
When dividing 2307 by 581, we get 3 with a remainder of 564.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1743 from 2307 leaves us with 564.
Bring next digit (8) of the dividend behind the 564 and repeat the process: 5648 / 581

Step 5:
5648 divided by 581 is 9 with a remainder of 419.
Put 9 as the next digit of the answer. 
Result so far: 139.0
The remainder is 419 after subtracting 5229 from 5648.
Fetch the next digit (4) from the dividend, attach it to 419 and continue: 4194 / 581

Let's proceed to step 6:
When dividing 4194 by 581, we get 7 with a remainder of 127.
Write down 7 as next digit of the result. 
Result so far: 1397.0
Deduct 4067 from 4194 and we're left with 127.
Include the next digit (9) from the dividend after 127, then repeat: 1279 / 581

On to step 7:
The number 581 fits into 1279 2 times, leaving a remainder of 117.
The number 2 becomes the next digit in our result. 
Result so far: 13972.0
The remainder is 117 after subtracting 1162 from 1279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 8:
581 goes into 1170 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 13972.2
If we take 1162 away from 1170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
581 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 13972.2
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
The number 581 fits into 800 1 times, leaving a remainder of 219.
The next digit of our result is 1. 
Result so far: 13972.201
If we subtract 581 from 800, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Let's proceed to step 11:
2190 divided by 581 is 3 with a remainder of 447.
Write down 3 as next digit of the result. 
Result so far: 13972.2013
Deduct 1743 from 2190 and we're left with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Going ahead to step 12:
581 can be fit into 4470 7 times, resulting in a remainder of 403.
Record the quotient 7 as the next digit in the result. 
Result so far: 13972.20137
If we subtract 4067 from 4470, we get 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Advancing to step 13:
When dividing 4030 by 581, we get 6 with a remainder of 544.
Use 6 as the next digit of our solution. 
Result so far: 13972.201376
If we take 3486 away from 4030, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 14:
581 goes into 5440 9 times with a remainder of 211.
Record the quotient 9 as the next digit in the result. 
Result so far: 13972.2013769
Subtracting 5229 from 5440 leaves us with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 15:
If we divide 2110 by 581, we get 3 and a remainder of 367.
Use 3 as the next digit of our solution. 
Result so far: 13972.20137693
Deduct 1743 from 2110 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

The final outcome is 13972.20137693, with a leftover of 3.67e-07.
