We're dividing 68104508 by 421 
Let's see how many times 421 fits into 68104508.

On to step 1:
421 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 421

Let's proceed to step 2:
When dividing 68 by 421, we get 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 421

Going ahead to step 3:
The number 421 fits into 681 1 times, leaving a remainder of 260.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 421 from 681 leaves us with 260.
Bring next digit (0) of the dividend behind the 260 and repeat the process: 2600 / 421

Step 4:
2600 divided by 421 is 6 with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 2526 from 2600 and we're left with 74.
Include the next digit (4) from the dividend after 74, then repeat: 744 / 421

Step 5:
The number 421 fits into 744 1 times, leaving a remainder of 323.
Use 1 as the next digit of our solution. 
Result so far: 161.0
If we take 421 away from 744, we end up with 323.
Grab the next digit (5) from the dividend, add it to 323, then carry on: 3235 / 421

Moving on to step 6:
421 can be fit into 3235 7 times, resulting in a remainder of 288.
The number 7 becomes the next digit in our result. 
Result so far: 1617.0
If we take 2947 away from 3235, we end up with 288.
Grab the next digit (0) from the dividend, add it to 288, then carry on: 2880 / 421

Let's proceed to step 7:
421 can be fit into 2880 6 times, resulting in a remainder of 354.
The number 6 becomes the next digit in our result. 
Result so far: 16176.0
Deduct 2526 from 2880 and we're left with 354.
Bring next digit (8) of the dividend behind the 354 and repeat the process: 3548 / 421

Step 8:
421 can be fit into 3548 8 times, resulting in a remainder of 180.
Record the quotient 8 as the next digit in the result. 
Result so far: 161768.0
If we subtract 3368 from 3548, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 9:
1800 divided by 421 is 4 with a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 161768.4
Deduct 1684 from 1800 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 10:
When dividing 1160 by 421, we get 2 with a remainder of 318.
Put 2 as the next digit of the answer. 
Result so far: 161768.42
Subtract 842 from 1160 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Step 11:
When dividing 3180 by 421, we get 7 with a remainder of 233.
The next digit of our result is 7. 
Result so far: 161768.427
The remainder is 233 after subtracting 2947 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 12:
421 can be fit into 2330 5 times, resulting in a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 161768.4275
The remainder is 225 after subtracting 2105 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 13:
421 goes into 2250 5 times with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 161768.42755
Subtract 2105 from 2250 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final result is 161768.42755 with a remainder of 0.000145.
