We're dividing 1057 by 86 
Our goal is to divide 1057 by 86.

Step 1:
86 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 86

Advancing to step 2:
The number 86 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 86

Going ahead to step 3:
105 divided by 86 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 86 from 105, we get 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 86

Going ahead to step 4:
When dividing 197 by 86, we get 2 with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 172 from 197 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 5:
86 goes into 250 2 times with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 12.2
Subtract 172 from 250 to 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.

Advancing to step 6:
If we divide 780 by 86, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 12.29
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.

Let's proceed to step 7:
The number 86 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 12.29
If we subtract 0 from 60, we 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:
86 goes into 600 6 times with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 12.2906
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.

Advancing to step 9:
If we divide 840 by 86, we get 9 and a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 12.29069
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.

Step 10:
The number 86 fits into 660 7 times, leaving a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 12.290697
If we subtract 602 from 660, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
If we divide 580 by 86, we get 6 and a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 12.2906976
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.

Moving on to step 12:
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: 12.29069767
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.

After the division, we end up with 12.29069767 and a remainder of 3.8e-08.
