106603 divided by 86 
We want to divide 106603 by 86.

Moving on to step 1:
1 divided by 86 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 86

Advancing to step 2:
86 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 86

Step 3:
86 goes into 106 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 86 away from 106, we end up with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 86

Step 4:
206 divided by 86 is 2 with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 34 after subtracting 172 from 206.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 86

Advancing to step 5:
86 can be fit into 340 3 times, resulting in a remainder of 82.
The next digit of our result is 3. 
Result so far: 123.0
The remainder is 82 after subtracting 258 from 340.
Fetch the next digit (3) from the dividend, attach it to 82 and continue: 823 / 86

Going ahead to step 6:
The number 86 fits into 823 9 times, leaving a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 1239.0
If we take 774 away from 823, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
If we divide 490 by 86, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 1239.5
Subtract 430 from 490 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.

Step 8:
86 can be fit into 600 6 times, resulting in a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 1239.56
Subtracting 516 from 600 leaves us 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.

On to step 9:
If we divide 840 by 86, we get 9 and a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 1239.569
Subtract 774 from 840 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
The number 86 fits into 660 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 1239.5697
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.

On to step 11:
The number 86 fits into 580 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 1239.56976
Deduct 516 from 580 and we're left 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.

Moving on to step 12:
If we divide 640 by 86, we get 7 and a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 1239.569767
Deduct 602 from 640 and we're left with 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:
When dividing 380 by 86, we get 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 1239.5697674
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
When dividing 360 by 86, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 1239.56976744
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 1239.56976744 with a remaining 1.6e-08.
