99512465 ÷ 686 
We're looking to find how many times 686 goes into 99512465.

On to step 1:
686 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 686

Advancing to step 2:
When dividing 99 by 686, we get 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 686

Let's proceed to step 3:
686 goes into 995 1 times with a remainder of 309.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 686 from 995 leaves us with 309.
Grab the next digit (1) from the dividend, add it to 309, then carry on: 3091 / 686

Let's proceed to step 4:
686 can be fit into 3091 4 times, resulting in a remainder of 347.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 2744 from 3091, we get 347.
Fetch the next digit (2) from the dividend, attach it to 347 and continue: 3472 / 686

On to step 5:
The number 686 fits into 3472 5 times, leaving a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 145.0
Subtract 3430 from 3472 to get 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 686

Going ahead to step 6:
424 divided by 686 is 0 with a remainder of 424.
Record the quotient 0 as the next digit in the result. 
Result so far: 1450.0
Deduct 0 from 424 and we're left with 424.
Take the next digit (6) from the dividend and append it to 424, then repeat: 4246 / 686

Advancing to step 7:
4246 divided by 686 is 6 with a remainder of 130.
Record the quotient 6 as the next digit in the result. 
Result so far: 14506.0
Deduct 4116 from 4246 and we're left with 130.
Include the next digit (5) from the dividend after 130, then repeat: 1305 / 686

On to step 8:
1305 divided by 686 is 1 with a remainder of 619.
Write down 1 as next digit of the result. 
Result so far: 145061.0
If we take 686 away from 1305, we end up with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

On to step 9:
When dividing 6190 by 686, we get 9 with a remainder of 16.
The next digit of our result is 9. 
Result so far: 145061.9
Deduct 6174 from 6190 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.

Going ahead to step 10:
686 goes into 160 0 times with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 145061.9
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
The number 686 fits into 1600 2 times, leaving a remainder of 228.
Write down 2 as next digit of the result. 
Result so far: 145061.902
The remainder is 228 after subtracting 1372 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 12:
The number 686 fits into 2280 3 times, leaving a remainder of 222.
Put 3 as the next digit of the answer. 
Result so far: 145061.9023
If we subtract 2058 from 2280, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 13:
686 can be fit into 2220 3 times, resulting in a remainder of 162.
Use 3 as the next digit of our solution. 
Result so far: 145061.90233
Deduct 2058 from 2220 and we're left 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.

Our division results in 145061.90233 with a remaining 0.000162.
