90066 ÷ 86 
We're looking to find how many times 86 goes into 90066.

Advancing to step 1:
86 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 86

Step 2:
If we divide 90 by 86, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 86 from 90, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 86

Moving on to step 3:
86 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 40, we get 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 86

On to step 4:
406 divided by 86 is 4 with a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
The remainder is 62 after subtracting 344 from 406.
Fetch the next digit (6) from the dividend, attach it to 62 and continue: 626 / 86

On to step 5:
86 can be fit into 626 7 times, resulting in a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 1047.0
If we take 602 away from 626, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 6:
86 goes into 240 2 times with a remainder of 68.
The next digit of our result is 2. 
Result so far: 1047.2
If we take 172 away from 240, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
If we divide 680 by 86, we get 7 and a remainder of 78.
Use 7 as the next digit of our solution. 
Result so far: 1047.27
If we subtract 602 from 680, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 8:
780 divided by 86 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 1047.279
Deduct 774 from 780 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
86 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1047.279
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
If we divide 600 by 86, we get 6 and a remainder of 84.
The next digit of our result is 6. 
Result so far: 1047.27906
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 11:
When dividing 840 by 86, we get 9 with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 1047.279069
If we take 774 away from 840, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
86 goes into 660 7 times with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 1047.2790697
Subtracting 602 from 660 leaves us 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.

Going ahead to step 13:
86 goes into 580 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 1047.27906976
Subtracting 516 from 580 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 1047.27906976, with a leftover of 6.4e-08.
