We look at the division of 68976640 by 406 
We're looking to find how many times 406 goes into 68976640.

Step 1:
The number 406 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 406

Let's proceed to step 2:
When dividing 68 by 406, we get 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Take the next digit (9) from the dividend and append it to 68, then repeat: 689 / 406

Let's proceed to step 3:
406 can be fit into 689 1 times, resulting in a remainder of 283.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 406 from 689, we get 283.
Append the next digit (7) from the dividend to 283 and continue with: 2837 / 406

Let's proceed to step 4:
The number 406 fits into 2837 6 times, leaving a remainder of 401.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 2436 from 2837, we get 401.
Fetch the next digit (6) from the dividend, attach it to 401 and continue: 4016 / 406

On to step 5:
4016 divided by 406 is 9 with a remainder of 362.
The next digit of our result is 9. 
Result so far: 169.0
If we subtract 3654 from 4016, we get 362.
Take the next digit (6) from the dividend and append it to 362, then repeat: 3626 / 406

Going ahead to step 6:
3626 divided by 406 is 8 with a remainder of 378.
The number 8 becomes the next digit in our result. 
Result so far: 1698.0
Subtract 3248 from 3626 to get 378.
Bring next digit (4) of the dividend behind the 378 and repeat the process: 3784 / 406

On to step 7:
406 can be fit into 3784 9 times, resulting in a remainder of 130.
The number 9 becomes the next digit in our result. 
Result so far: 16989.0
The remainder is 130 after subtracting 3654 from 3784.
Fetch the next digit (0) from the dividend, attach it to 130 and continue: 1300 / 406

Going ahead to step 8:
406 goes into 1300 3 times with a remainder of 82.
The next digit of our result is 3. 
Result so far: 169893.0
Subtracting 1218 from 1300 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 9:
When dividing 820 by 406, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 169893.2
If we take 812 away from 820, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
80 divided by 406 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 169893.2
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
The number 406 fits into 800 1 times, leaving a remainder of 394.
Record the quotient 1 as the next digit in the result. 
Result so far: 169893.201
The remainder is 394 after subtracting 406 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 12:
3940 divided by 406 is 9 with a remainder of 286.
Use 9 as the next digit of our solution. 
Result so far: 169893.2019
Deduct 3654 from 3940 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 13:
The number 406 fits into 2860 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 169893.20197
Subtract 2842 from 2860 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
406 can be fit into 180 0 times, resulting in a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 169893.20197
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 15:
When dividing 1800 by 406, we get 4 with a remainder of 176.
Put 4 as the next digit of the answer. 
Result so far: 169893.2019704
If we subtract 1624 from 1800, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 16:
When dividing 1760 by 406, we get 4 with a remainder of 136.
The next digit of our result is 4. 
Result so far: 169893.20197044
Subtracting 1624 from 1760 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 169893.20197044 and a remainder of 1.36e-07.
