86106660 ÷ 699 
Let's see how many times 699 fits into 86106660.

Going ahead to step 1:
8 divided by 699 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 699

Advancing to step 2:
The number 699 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 699

Advancing to step 3:
If we divide 861 by 699, we get 1 and a remainder of 162.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 699 from 861, we get 162.
Fetch the next digit (0) from the dividend, attach it to 162 and continue: 1620 / 699

Advancing to step 4:
The number 699 fits into 1620 2 times, leaving a remainder of 222.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1398 away from 1620, we end up with 222.
Bring next digit (6) of the dividend behind the 222 and repeat the process: 2226 / 699

Going ahead to step 5:
The number 699 fits into 2226 3 times, leaving a remainder of 129.
Write down 3 as next digit of the result. 
Result so far: 123.0
Subtract 2097 from 2226 to get 129.
Bring next digit (6) of the dividend behind the 129 and repeat the process: 1296 / 699

On to step 6:
699 can be fit into 1296 1 times, resulting in a remainder of 597.
Use 1 as the next digit of our solution. 
Result so far: 1231.0
Subtracting 699 from 1296 leaves us with 597.
Bring next digit (6) of the dividend behind the 597 and repeat the process: 5976 / 699

Going ahead to step 7:
699 can be fit into 5976 8 times, resulting in a remainder of 384.
Use 8 as the next digit of our solution. 
Result so far: 12318.0
Deduct 5592 from 5976 and we're left with 384.
Append the next digit (0) from the dividend to 384 and continue with: 3840 / 699

Let's proceed to step 8:
If we divide 3840 by 699, we get 5 and a remainder of 345.
The number 5 becomes the next digit in our result. 
Result so far: 123185.0
If we subtract 3495 from 3840, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Advancing to step 9:
The number 699 fits into 3450 4 times, leaving a remainder of 654.
The number 4 becomes the next digit in our result. 
Result so far: 123185.4
Deduct 2796 from 3450 and we're left with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

On to step 10:
699 goes into 6540 9 times with a remainder of 249.
Use 9 as the next digit of our solution. 
Result so far: 123185.49
If we take 6291 away from 6540, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 11:
If we divide 2490 by 699, we get 3 and a remainder of 393.
Write down 3 as next digit of the result. 
Result so far: 123185.493
The remainder is 393 after subtracting 2097 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Advancing to step 12:
If we divide 3930 by 699, we get 5 and a remainder of 435.
Use 5 as the next digit of our solution. 
Result so far: 123185.4935
Deduct 3495 from 3930 and we're left with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 13:
699 can be fit into 4350 6 times, resulting in a remainder of 156.
Put 6 as the next digit of the answer. 
Result so far: 123185.49356
The remainder is 156 after subtracting 4194 from 4350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 14:
The number 699 fits into 1560 2 times, leaving a remainder of 162.
Write down 2 as next digit of the result. 
Result so far: 123185.493562
Subtracting 1398 from 1560 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 15:
699 can be fit into 1620 2 times, resulting in a remainder of 222.
Put 2 as the next digit of the answer. 
Result so far: 123185.4935622
Subtracting 1398 from 1620 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

The final result is 123185.4935622 with a remainder of 2.22e-06.
