We're dividing 983158 by 86 
We want to divide 983158 by 86.

Moving on to step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 86

On to step 2:
86 can be fit into 98 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 86 from 98 to get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 86

Step 3:
When dividing 123 by 86, we get 1 with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 86 from 123 leaves us with 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 86

On to step 4:
86 can be fit into 371 4 times, resulting in a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Deduct 344 from 371 and we're left with 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 86

On to step 5:
The number 86 fits into 275 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 1143.0
If we take 258 away from 275, we end up with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 86

Advancing to step 6:
If we divide 178 by 86, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 11432.0
Subtract 172 from 178 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 86, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 11432.0
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.

Moving on to step 8:
When dividing 600 by 86, we get 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 11432.06
If we take 516 away from 600, we end up 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 9:
The number 86 fits into 840 9 times, leaving a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 11432.069
Subtracting 774 from 840 leaves us 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 10:
If we divide 660 by 86, we get 7 and a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 11432.0697
Deduct 602 from 660 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.

Let's proceed to step 11:
86 goes into 580 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 11432.06976
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
86 goes into 640 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 11432.069767
Subtract 602 from 640 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
86 can be fit into 380 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 11432.0697674
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
86 can be fit into 360 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 11432.06976744
If we take 344 away from 360, 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.

The final outcome is 11432.06976744, with a leftover of 1.6e-08.
