We look at the division of 58121332 by 81 
We want to figure out the number of times 58121332 can be divided by 81.

On to step 1:
81 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 81

Let's proceed to step 2:
81 can be fit into 58 0 times, resulting in a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Append the next digit (1) from the dividend to 58 and continue with: 581 / 81

Going ahead to step 3:
The number 81 fits into 581 7 times, leaving a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 567 from 581, we get 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 81

Going ahead to step 4:
81 can be fit into 142 1 times, resulting in a remainder of 61.
The next digit of our result is 1. 
Result so far: 71.0
The remainder is 61 after subtracting 81 from 142.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 81

Step 5:
If we divide 611 by 81, we get 7 and a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 717.0
Deduct 567 from 611 and we're left with 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 81

Advancing to step 6:
When dividing 443 by 81, we get 5 with a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 7175.0
Subtract 405 from 443 to get 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 81

Moving on to step 7:
81 goes into 383 4 times with a remainder of 59.
The number 4 becomes the next digit in our result. 
Result so far: 71754.0
If we subtract 324 from 383, we get 59.
Fetch the next digit (2) from the dividend, attach it to 59 and continue: 592 / 81

On to step 8:
When dividing 592 by 81, we get 7 with a remainder of 25.
The next digit of our result is 7. 
Result so far: 717547.0
Subtracting 567 from 592 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
250 divided by 81 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 717547.3
Deduct 243 from 250 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
The number 81 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 717547.3
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
81 goes into 700 8 times with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 717547.308
Subtract 648 from 700 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
81 goes into 520 6 times with a remainder of 34.
The next digit of our result is 6. 
Result so far: 717547.3086
If we take 486 away from 520, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
The number 81 fits into 340 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 717547.30864
If we take 324 away from 340, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
81 can be fit into 160 1 times, resulting in a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 717547.308641
Subtracting 81 from 160 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 15:
81 can be fit into 790 9 times, resulting in a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 717547.3086419
If we take 729 away from 790, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 16:
610 divided by 81 is 7 with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 717547.30864197
Deduct 567 from 610 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

In conclusion, the division gives 717547.30864197 with a balance of 4.3e-08.
