86342443 ÷ 591 
We want to figure out the number of times 86342443 can be divided by 591.

Let's proceed to step 1:
591 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 591

On to step 2:
When dividing 86 by 591, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 591

Let's proceed to step 3:
591 goes into 863 1 times with a remainder of 272.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 591 away from 863, we end up with 272.
Grab the next digit (4) from the dividend, add it to 272, then carry on: 2724 / 591

Advancing to step 4:
The number 591 fits into 2724 4 times, leaving a remainder of 360.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 2364 from 2724, we get 360.
Fetch the next digit (2) from the dividend, attach it to 360 and continue: 3602 / 591

Moving on to step 5:
3602 divided by 591 is 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 146.0
If we take 3546 away from 3602, we end up with 56.
Fetch the next digit (4) from the dividend, attach it to 56 and continue: 564 / 591

Let's proceed to step 6:
564 divided by 591 is 0 with a remainder of 564.
The number 0 becomes the next digit in our result. 
Result so far: 1460.0
The remainder is 564 after subtracting 0 from 564.
Grab the next digit (4) from the dividend, add it to 564, then carry on: 5644 / 591

Going ahead to step 7:
591 can be fit into 5644 9 times, resulting in a remainder of 325.
Put 9 as the next digit of the answer. 
Result so far: 14609.0
Subtract 5319 from 5644 to get 325.
Bring next digit (3) of the dividend behind the 325 and repeat the process: 3253 / 591

Step 8:
If we divide 3253 by 591, we get 5 and a remainder of 298.
The number 5 becomes the next digit in our result. 
Result so far: 146095.0
If we subtract 2955 from 3253, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 9:
2980 divided by 591 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 146095.5
Subtract 2955 from 2980 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
591 goes into 250 0 times with a remainder of 250.
The next digit of our result is 0. 
Result so far: 146095.5
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 11:
The number 591 fits into 2500 4 times, leaving a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 146095.504
Subtract 2364 from 2500 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 12:
1360 divided by 591 is 2 with a remainder of 178.
Record the quotient 2 as the next digit in the result. 
Result so far: 146095.5042
The remainder is 178 after subtracting 1182 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 13:
If we divide 1780 by 591, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 146095.50423
Deduct 1773 from 1780 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.

Let's proceed to step 14:
70 divided by 591 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 146095.50423
Subtract 0 from 70 to 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.

Advancing to step 15:
When dividing 700 by 591, we get 1 with a remainder of 109.
Use 1 as the next digit of our solution. 
Result so far: 146095.5042301
If we subtract 591 from 700, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 16:
When dividing 1090 by 591, we get 1 with a remainder of 499.
The number 1 becomes the next digit in our result. 
Result so far: 146095.50423011
Subtracting 591 from 1090 leaves us with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

In conclusion, the division gives 146095.50423011 with a balance of 4.99e-07.
