7424778 divided by 686 
We want to divide 7424778 by 686.

Step 1:
686 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 686

Moving on to step 2:
686 goes into 74 0 times with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Include the next digit (2) from the dividend after 74, then repeat: 742 / 686

Going ahead to step 3:
686 can be fit into 742 1 times, resulting in a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 686 away from 742, we end up with 56.
Grab the next digit (4) from the dividend, add it to 56, then carry on: 564 / 686

Advancing to step 4:
When dividing 564 by 686, we get 0 with a remainder of 564.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 564 after subtracting 0 from 564.
Fetch the next digit (7) from the dividend, attach it to 564 and continue: 5647 / 686

Let's proceed to step 5:
5647 divided by 686 is 8 with a remainder of 159.
Put 8 as the next digit of the answer. 
Result so far: 108.0
If we subtract 5488 from 5647, we get 159.
Append the next digit (7) from the dividend to 159 and continue with: 1597 / 686

Let's proceed to step 6:
1597 divided by 686 is 2 with a remainder of 225.
Put 2 as the next digit of the answer. 
Result so far: 1082.0
Subtracting 1372 from 1597 leaves us with 225.
Fetch the next digit (8) from the dividend, attach it to 225 and continue: 2258 / 686

Step 7:
686 goes into 2258 3 times with a remainder of 200.
Write down 3 as next digit of the result. 
Result so far: 10823.0
Deduct 2058 from 2258 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 8:
686 can be fit into 2000 2 times, resulting in a remainder of 628.
Put 2 as the next digit of the answer. 
Result so far: 10823.2
If we take 1372 away from 2000, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Going ahead to step 9:
686 goes into 6280 9 times with a remainder of 106.
Use 9 as the next digit of our solution. 
Result so far: 10823.29
Subtract 6174 from 6280 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 10:
1060 divided by 686 is 1 with a remainder of 374.
The number 1 becomes the next digit in our result. 
Result so far: 10823.291
If we subtract 686 from 1060, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Advancing to step 11:
The number 686 fits into 3740 5 times, leaving a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 10823.2915
Deduct 3430 from 3740 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 12:
The number 686 fits into 3100 4 times, leaving a remainder of 356.
The number 4 becomes the next digit in our result. 
Result so far: 10823.29154
Deduct 2744 from 3100 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 13:
686 can be fit into 3560 5 times, resulting in a remainder of 130.
The next digit of our result is 5. 
Result so far: 10823.291545
Subtracting 3430 from 3560 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 14:
1300 divided by 686 is 1 with a remainder of 614.
The next digit of our result is 1. 
Result so far: 10823.2915451
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.

Advancing to step 15:
686 can be fit into 6140 8 times, resulting in a remainder of 652.
Write down 8 as next digit of the result. 
Result so far: 10823.29154518
If we take 5488 away from 6140, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Our division results in 10823.29154518 with a remaining 6.52e-07.
