325429 ÷ 86 
We want to figure out the number of times 325429 can be divided by 86.

On to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 86

On to step 2:
When dividing 32 by 86, we get 0 with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 86

Moving on to step 3:
If we divide 325 by 86, we get 3 and a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 258 away from 325, we end up with 67.
Fetch the next digit (4) from the dividend, attach it to 67 and continue: 674 / 86

Going ahead to step 4:
If we divide 674 by 86, we get 7 and a remainder of 72.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we subtract 602 from 674, we get 72.
Append the next digit (2) from the dividend to 72 and continue with: 722 / 86

Going ahead to step 5:
If we divide 722 by 86, we get 8 and a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 378.0
If we subtract 688 from 722, we get 34.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 86

Step 6:
86 goes into 349 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 3784.0
Subtract 344 from 349 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
86 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 3784.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
500 divided by 86 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 3784.05
The remainder is 70 after subtracting 430 from 500.
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 9:
The number 86 fits into 700 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 3784.058
If we subtract 688 from 700, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
When dividing 120 by 86, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 3784.0581
Subtract 86 from 120 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
340 divided by 86 is 3 with a remainder of 82.
The next digit of our result is 3. 
Result so far: 3784.05813
If we subtract 258 from 340, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 12:
If we divide 820 by 86, we get 9 and a remainder of 46.
The next digit of our result is 9. 
Result so far: 3784.058139
If we subtract 774 from 820, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
86 can be fit into 460 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 3784.0581395
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 3784.05813953
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 3784.05813953 with a remaining 4.2e-08.
