We look at the division of 40028230 by 686 
We want to figure out the number of times 40028230 can be divided by 686.

Let's proceed to step 1:
When dividing 4 by 686, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 686

On to step 2:
If we divide 40 by 686, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 686

Going ahead to step 3:
The number 686 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 400 after subtracting 0 from 400.
Grab the next digit (2) from the dividend, add it to 400, then carry on: 4002 / 686

Step 4:
If we divide 4002 by 686, we get 5 and a remainder of 572.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 572 after subtracting 3430 from 4002.
Grab the next digit (8) from the dividend, add it to 572, then carry on: 5728 / 686

Let's proceed to step 5:
5728 divided by 686 is 8 with a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Deduct 5488 from 5728 and we're left with 240.
Fetch the next digit (2) from the dividend, attach it to 240 and continue: 2402 / 686

On to step 6:
2402 divided by 686 is 3 with a remainder of 344.
Put 3 as the next digit of the answer. 
Result so far: 583.0
If we take 2058 away from 2402, we end up with 344.
Bring next digit (3) of the dividend behind the 344 and repeat the process: 3443 / 686

Going ahead to step 7:
3443 divided by 686 is 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 5835.0
If we subtract 3430 from 3443, we get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 686

Let's proceed to step 8:
130 divided by 686 is 0 with a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 58350.0
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 9:
The number 686 fits into 1300 1 times, leaving a remainder of 614.
Use 1 as the next digit of our solution. 
Result so far: 58350.1
Subtracting 686 from 1300 leaves us with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Moving on to step 10:
When dividing 6140 by 686, we get 8 with a remainder of 652.
Write down 8 as next digit of the result. 
Result so far: 58350.18
Subtract 5488 from 6140 to get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

On to step 11:
686 can be fit into 6520 9 times, resulting in a remainder of 346.
Record the quotient 9 as the next digit in the result. 
Result so far: 58350.189
If we subtract 6174 from 6520, we get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 12:
686 goes into 3460 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 58350.1895
Subtracting 3430 from 3460 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
The number 686 fits into 300 0 times, leaving a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 58350.1895
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 14:
3000 divided by 686 is 4 with a remainder of 256.
Use 4 as the next digit of our solution. 
Result so far: 58350.189504
If we subtract 2744 from 3000, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 15:
686 goes into 2560 3 times with a remainder of 502.
The number 3 becomes the next digit in our result. 
Result so far: 58350.1895043
If we take 2058 away from 2560, we end up with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Advancing to step 16:
When dividing 5020 by 686, we get 7 with a remainder of 218.
Put 7 as the next digit of the answer. 
Result so far: 58350.18950437
The remainder is 218 after subtracting 4802 from 5020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The final outcome is 58350.18950437, with a leftover of 2.18e-07.
