We divide 307043 by 86
Our goal is to divide 307043 by 86.

Step 1:
86 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 86

Advancing to step 2:
When dividing 30 by 86, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 86

Step 3:
The number 86 fits into 307 3 times, leaving a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 49 after subtracting 258 from 307.
Fetch the next digit (0) from the dividend, attach it to 49 and continue: 490 / 86

Moving on to step 4:
The number 86 fits into 490 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtracting 430 from 490 leaves us with 60.
Grab the next digit (4) from the dividend, add it to 60, then carry on: 604 / 86

Advancing to step 5:
86 goes into 604 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 357.0
Deduct 602 from 604 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 86

Going ahead to step 6:
23 divided by 86 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 3570.0
The remainder is 23 after subtracting 0 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
When dividing 230 by 86, we get 2 with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 3570.2
Deduct 172 from 230 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
When dividing 580 by 86, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 3570.26
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
86 can be fit into 640 7 times, resulting in a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 3570.267
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 3570.2674
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
If we divide 360 by 86, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 3570.26744
Subtracting 344 from 360 leaves us 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.

The final outcome is 3570.26744, with a leftover of 1.6e-05.
