Let's divide 169243 by 86
We want to divide 169243 by 86.

Moving on to step 1:
86 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 86

Let's proceed to step 2:
86 goes into 16 0 times with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 86

Advancing to step 3:
If we divide 169 by 86, we get 1 and a remainder of 83.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 86 from 169, we get 83.
Bring next digit (2) of the dividend behind the 83 and repeat the process: 832 / 86

Advancing to step 4:
86 can be fit into 832 9 times, resulting in a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 774 from 832 and we're left with 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 86

Advancing to step 5:
If we divide 584 by 86, we get 6 and a remainder of 68.
The next digit of our result is 6. 
Result so far: 196.0
If we take 516 away from 584, we end up with 68.
Fetch the next digit (3) from the dividend, attach it to 68 and continue: 683 / 86

Let's proceed to step 6:
86 goes into 683 7 times with a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 1967.0
Subtract 602 from 683 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 7:
If we divide 810 by 86, we get 9 and a remainder of 36.
The next digit of our result is 9. 
Result so far: 1967.9
Subtract 774 from 810 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 8:
86 can be fit into 360 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 1967.94
Deduct 344 from 360 and we're left 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.

Advancing to step 9:
The number 86 fits into 160 1 times, leaving a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 1967.941
Subtracting 86 from 160 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 10:
86 can be fit into 740 8 times, resulting in a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 1967.9418
If we subtract 688 from 740, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
520 divided by 86 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 1967.94186
The remainder is 4 after subtracting 516 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
If we divide 40 by 86, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 1967.94186
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
400 divided by 86 is 4 with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 1967.9418604
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
The number 86 fits into 560 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 1967.94186046
Deduct 516 from 560 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 1967.94186046 and a remainder of 4.4e-08.
