We look at the division of 67536318 by 421 
Our goal is to divide 67536318 by 421.

Going ahead to step 1:
When dividing 6 by 421, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 421

Step 2:
If we divide 67 by 421, we get 0 and a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 421

Let's proceed to step 3:
The number 421 fits into 675 1 times, leaving a remainder of 254.
The next digit of our result is 1. 
Result so far: 1.0
If we take 421 away from 675, we end up with 254.
Bring next digit (3) of the dividend behind the 254 and repeat the process: 2543 / 421

On to step 4:
421 goes into 2543 6 times with a remainder of 17.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 2526 from 2543, we get 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 421

Step 5:
421 can be fit into 176 0 times, resulting in a remainder of 176.
The next digit of our result is 0. 
Result so far: 160.0
Deduct 0 from 176 and we're left with 176.
Take the next digit (3) from the dividend and append it to 176, then repeat: 1763 / 421

Going ahead to step 6:
421 goes into 1763 4 times with a remainder of 79.
Record the quotient 4 as the next digit in the result. 
Result so far: 1604.0
Subtract 1684 from 1763 to get 79.
Bring next digit (1) of the dividend behind the 79 and repeat the process: 791 / 421

Moving on to step 7:
The number 421 fits into 791 1 times, leaving a remainder of 370.
Record the quotient 1 as the next digit in the result. 
Result so far: 16041.0
If we take 421 away from 791, we end up with 370.
Take the next digit (8) from the dividend and append it to 370, then repeat: 3708 / 421

On to step 8:
The number 421 fits into 3708 8 times, leaving a remainder of 340.
Write down 8 as next digit of the result. 
Result so far: 160418.0
Deduct 3368 from 3708 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 9:
If we divide 3400 by 421, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 160418.8
Subtract 3368 from 3400 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
421 goes into 320 0 times with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 160418.8
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 11:
The number 421 fits into 3200 7 times, leaving a remainder of 253.
The next digit of our result is 7. 
Result so far: 160418.807
Subtracting 2947 from 3200 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 12:
When dividing 2530 by 421, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 160418.8076
Subtracting 2526 from 2530 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
40 divided by 421 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 160418.8076
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
421 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 160418.8076
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 160418.8076 with a remaining 4e-05.
