68401091 ÷ 407 
We want to divide 68401091 by 407.

Moving on to step 1:
6 divided by 407 is 0 with a remainder of 6.
Write down 0 as next digit of 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 / 407

Advancing to step 2:
The number 407 fits into 68 0 times, leaving a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Bring next digit (4) of the dividend behind the 68 and repeat the process: 684 / 407

Step 3:
407 goes into 684 1 times with a remainder of 277.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 407 from 684, we get 277.
Grab the next digit (0) from the dividend, add it to 277, then carry on: 2770 / 407

Going ahead to step 4:
If we divide 2770 by 407, we get 6 and a remainder of 328.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 2442 from 2770 leaves us with 328.
Fetch the next digit (1) from the dividend, attach it to 328 and continue: 3281 / 407

Moving on to step 5:
When dividing 3281 by 407, we get 8 with a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
Subtracting 3256 from 3281 leaves us with 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 407

Step 6:
250 divided by 407 is 0 with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 1680.0
If we subtract 0 from 250, we get 250.
Fetch the next digit (9) from the dividend, attach it to 250 and continue: 2509 / 407

Step 7:
2509 divided by 407 is 6 with a remainder of 67.
Put 6 as the next digit of the answer. 
Result so far: 16806.0
If we take 2442 away from 2509, we end up with 67.
Bring next digit (1) of the dividend behind the 67 and repeat the process: 671 / 407

Going ahead to step 8:
The number 407 fits into 671 1 times, leaving a remainder of 264.
Use 1 as the next digit of our solution. 
Result so far: 168061.0
Deduct 407 from 671 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 9:
407 goes into 2640 6 times with a remainder of 198.
Put 6 as the next digit of the answer. 
Result so far: 168061.6
Subtracting 2442 from 2640 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 10:
407 can be fit into 1980 4 times, resulting in a remainder of 352.
The number 4 becomes the next digit in our result. 
Result so far: 168061.64
The remainder is 352 after subtracting 1628 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 11:
If we divide 3520 by 407, we get 8 and a remainder of 264.
Put 8 as the next digit of the answer. 
Result so far: 168061.648
If we subtract 3256 from 3520, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 12:
407 goes into 2640 6 times with a remainder of 198.
Record the quotient 6 as the next digit in the result. 
Result so far: 168061.6486
Deduct 2442 from 2640 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 13:
When dividing 1980 by 407, we get 4 with a remainder of 352.
Write down 4 as next digit of the result. 
Result so far: 168061.64864
If we subtract 1628 from 1980, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 14:
3520 divided by 407 is 8 with a remainder of 264.
Write down 8 as next digit of the result. 
Result so far: 168061.648648
If we take 3256 away from 3520, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 15:
When dividing 2640 by 407, we get 6 with a remainder of 198.
The next digit of our result is 6. 
Result so far: 168061.6486486
Subtracting 2442 from 2640 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 16:
1980 divided by 407 is 4 with a remainder of 352.
Use 4 as the next digit of our solution. 
Result so far: 168061.64864864
Deduct 1628 from 1980 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The quotient of the division is 168061.64864864, and the remainder is 3.52e-07.
