Let's divide 11458343 by 581
We're looking to find how many times 581 goes into 11458343.

Advancing to step 1:
When dividing 1 by 581, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 581

Moving on to step 2:
581 goes into 11 0 times with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 581

Moving on to step 3:
581 can be fit into 114 0 times, resulting in a remainder of 114.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 114 after subtracting 0 from 114.
Grab the next digit (5) from the dividend, add it to 114, then carry on: 1145 / 581

Going ahead to step 4:
When dividing 1145 by 581, we get 1 with a remainder of 564.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 564 after subtracting 581 from 1145.
Grab the next digit (8) from the dividend, add it to 564, then carry on: 5648 / 581

Advancing to step 5:
581 goes into 5648 9 times with a remainder of 419.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 5229 from 5648 to get 419.
Include the next digit (3) from the dividend after 419, then repeat: 4193 / 581

Step 6:
581 can be fit into 4193 7 times, resulting in a remainder of 126.
Put 7 as the next digit of the answer. 
Result so far: 197.0
If we subtract 4067 from 4193, we get 126.
Include the next digit (4) from the dividend after 126, then repeat: 1264 / 581

On to step 7:
When dividing 1264 by 581, we get 2 with a remainder of 102.
Put 2 as the next digit of the answer. 
Result so far: 1972.0
Subtracting 1162 from 1264 leaves us with 102.
Grab the next digit (3) from the dividend, add it to 102, then carry on: 1023 / 581

Let's proceed to step 8:
581 goes into 1023 1 times with a remainder of 442.
Write down 1 as next digit of the result. 
Result so far: 19721.0
Subtract 581 from 1023 to get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 9:
4420 divided by 581 is 7 with a remainder of 353.
Use 7 as the next digit of our solution. 
Result so far: 19721.7
If we subtract 4067 from 4420, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Going ahead to step 10:
581 can be fit into 3530 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 19721.76
The remainder is 44 after subtracting 3486 from 3530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
440 divided by 581 is 0 with a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 19721.76
The remainder is 440 after subtracting 0 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 12:
581 can be fit into 4400 7 times, resulting in a remainder of 333.
Write down 7 as next digit of the result. 
Result so far: 19721.7607
If we subtract 4067 from 4400, we get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

On to step 13:
If we divide 3330 by 581, we get 5 and a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 19721.76075
If we take 2905 away from 3330, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 14:
581 can be fit into 4250 7 times, resulting in a remainder of 183.
Use 7 as the next digit of our solution. 
Result so far: 19721.760757
Subtract 4067 from 4250 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 15:
When dividing 1830 by 581, we get 3 with a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 19721.7607573
If we take 1743 away from 1830, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 16:
If we divide 870 by 581, we get 1 and a remainder of 289.
Record the quotient 1 as the next digit in the result. 
Result so far: 19721.76075731
Deduct 581 from 870 and we're left with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

After the division, we end up with 19721.76075731 and a remainder of 2.89e-07.
