We look at the division of 13985354 by 86 
Let's see how many times 86 fits into 13985354.

Step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 86

Going ahead to step 2:
13 divided by 86 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 86

Moving on to step 3:
139 divided by 86 is 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 53 after subtracting 86 from 139.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 86

Advancing to step 4:
86 can be fit into 538 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 516 away from 538, we end up with 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 86

Let's proceed to step 5:
225 divided by 86 is 2 with a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
If we take 172 away from 225, we end up with 53.
Append the next digit (3) from the dividend to 53 and continue with: 533 / 86

Advancing to step 6:
86 can be fit into 533 6 times, resulting in a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 1626.0
If we subtract 516 from 533, we get 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 86

Let's proceed to step 7:
When dividing 175 by 86, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 16262.0
Subtract 172 from 175 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 86

Moving on to step 8:
86 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 162620.0
If we subtract 0 from 34, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
The number 86 fits into 340 3 times, leaving a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 162620.3
Subtract 258 from 340 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 10:
When dividing 820 by 86, we get 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 162620.39
Deduct 774 from 820 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
86 can be fit into 460 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 162620.395
If we subtract 430 from 460, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 162620.3953
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
When dividing 420 by 86, we get 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 162620.39534
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
When dividing 760 by 86, we get 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 162620.395348
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 15:
86 goes into 720 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 162620.3953488
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 162620.3953488 with a remaining 3.2e-07.
