Let's divide 86699672 by 389
We want to divide 86699672 by 389.

On to step 1:
8 divided by 389 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 389

Let's proceed to step 2:
86 divided by 389 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 389

Moving on to step 3:
If we divide 866 by 389, we get 2 and a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 88 after subtracting 778 from 866.
Grab the next digit (9) from the dividend, add it to 88, then carry on: 889 / 389

Moving on to step 4:
The number 389 fits into 889 2 times, leaving a remainder of 111.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 778 from 889, we get 111.
Fetch the next digit (9) from the dividend, attach it to 111 and continue: 1119 / 389

Moving on to step 5:
1119 divided by 389 is 2 with a remainder of 341.
Put 2 as the next digit of the answer. 
Result so far: 222.0
The remainder is 341 after subtracting 778 from 1119.
Take the next digit (6) from the dividend and append it to 341, then repeat: 3416 / 389

Step 6:
The number 389 fits into 3416 8 times, leaving a remainder of 304.
Write down 8 as next digit of the result. 
Result so far: 2228.0
Deduct 3112 from 3416 and we're left with 304.
Grab the next digit (7) from the dividend, add it to 304, then carry on: 3047 / 389

Advancing to step 7:
If we divide 3047 by 389, we get 7 and a remainder of 324.
Write down 7 as next digit of the result. 
Result so far: 22287.0
Subtract 2723 from 3047 to get 324.
Fetch the next digit (2) from the dividend, attach it to 324 and continue: 3242 / 389

Advancing to step 8:
If we divide 3242 by 389, we get 8 and a remainder of 130.
Use 8 as the next digit of our solution. 
Result so far: 222878.0
The remainder is 130 after subtracting 3112 from 3242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 9:
389 can be fit into 1300 3 times, resulting in a remainder of 133.
Record the quotient 3 as the next digit in the result. 
Result so far: 222878.3
If we take 1167 away from 1300, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 10:
389 goes into 1330 3 times with a remainder of 163.
Record the quotient 3 as the next digit in the result. 
Result so far: 222878.33
Subtracting 1167 from 1330 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

The final outcome is 222878.33, with a leftover of 0.163.
