We look at the division of 8406913 by 689 
We want to figure out the number of times 8406913 can be divided by 689.

Step 1:
The number 689 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 689

Advancing to step 2:
If we divide 84 by 689, we get 0 and a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 689

On to step 3:
If we divide 840 by 689, we get 1 and a remainder of 151.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 689 from 840 leaves us with 151.
Append the next digit (6) from the dividend to 151 and continue with: 1516 / 689

On to step 4:
1516 divided by 689 is 2 with a remainder of 138.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 1378 from 1516 and we're left with 138.
Grab the next digit (9) from the dividend, add it to 138, then carry on: 1389 / 689

Step 5:
689 can be fit into 1389 2 times, resulting in a remainder of 11.
The next digit of our result is 2. 
Result so far: 122.0
The remainder is 11 after subtracting 1378 from 1389.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 689

Step 6:
111 divided by 689 is 0 with a remainder of 111.
Write down 0 as next digit of the result. 
Result so far: 1220.0
If we take 0 away from 111, we end up with 111.
Fetch the next digit (3) from the dividend, attach it to 111 and continue: 1113 / 689

Step 7:
The number 689 fits into 1113 1 times, leaving a remainder of 424.
Use 1 as the next digit of our solution. 
Result so far: 12201.0
The remainder is 424 after subtracting 689 from 1113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 8:
689 can be fit into 4240 6 times, resulting in a remainder of 106.
The number 6 becomes the next digit in our result. 
Result so far: 12201.6
Subtract 4134 from 4240 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.

On to step 9:
689 goes into 1060 1 times with a remainder of 371.
The number 1 becomes the next digit in our result. 
Result so far: 12201.61
Subtract 689 from 1060 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Step 10:
689 can be fit into 3710 5 times, resulting in a remainder of 265.
The next digit of our result is 5. 
Result so far: 12201.615
The remainder is 265 after subtracting 3445 from 3710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 11:
689 can be fit into 2650 3 times, resulting in a remainder of 583.
Put 3 as the next digit of the answer. 
Result so far: 12201.6153
Subtract 2067 from 2650 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Advancing to step 12:
5830 divided by 689 is 8 with a remainder of 318.
Put 8 as the next digit of the answer. 
Result so far: 12201.61538
If we take 5512 away from 5830, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 13:
If we divide 3180 by 689, we get 4 and a remainder of 424.
The number 4 becomes the next digit in our result. 
Result so far: 12201.615384
Subtract 2756 from 3180 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 14:
When dividing 4240 by 689, we get 6 with a remainder of 106.
Use 6 as the next digit of our solution. 
Result so far: 12201.6153846
If we take 4134 away from 4240, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 15:
If we divide 1060 by 689, we get 1 and a remainder of 371.
Write down 1 as next digit of the result. 
Result so far: 12201.61538461
Subtract 689 from 1060 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

After the division, we end up with 12201.61538461 and a remainder of 3.71e-07.
