We look at the division of 64761927 by 421 
We want to figure out the number of times 64761927 can be divided by 421.

On to step 1:
421 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 421

Advancing to step 2:
If we divide 64 by 421, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (7) from the dividend, add it to 64, then carry on: 647 / 421

Let's proceed to step 3:
When dividing 647 by 421, we get 1 with a remainder of 226.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 421 from 647 to get 226.
Include the next digit (6) from the dividend after 226, then repeat: 2266 / 421

On to step 4:
When dividing 2266 by 421, we get 5 with a remainder of 161.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 2105 from 2266 to get 161.
Fetch the next digit (1) from the dividend, attach it to 161 and continue: 1611 / 421

On to step 5:
If we divide 1611 by 421, we get 3 and a remainder of 348.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
The remainder is 348 after subtracting 1263 from 1611.
Take the next digit (9) from the dividend and append it to 348, then repeat: 3489 / 421

Let's proceed to step 6:
3489 divided by 421 is 8 with a remainder of 121.
Put 8 as the next digit of the answer. 
Result so far: 1538.0
Subtracting 3368 from 3489 leaves us with 121.
Fetch the next digit (2) from the dividend, attach it to 121 and continue: 1212 / 421

Advancing to step 7:
When dividing 1212 by 421, we get 2 with a remainder of 370.
Write down 2 as next digit of the result. 
Result so far: 15382.0
Subtracting 842 from 1212 leaves us with 370.
Fetch the next digit (7) from the dividend, attach it to 370 and continue: 3707 / 421

Advancing to step 8:
The number 421 fits into 3707 8 times, leaving a remainder of 339.
The number 8 becomes the next digit in our result. 
Result so far: 153828.0
If we take 3368 away from 3707, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Step 9:
When dividing 3390 by 421, we get 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 153828.8
If we subtract 3368 from 3390, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
If we divide 220 by 421, we get 0 and a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 153828.8
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
The number 421 fits into 2200 5 times, leaving a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 153828.805
If we subtract 2105 from 2200, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 12:
421 can be fit into 950 2 times, resulting in a remainder of 108.
The next digit of our result is 2. 
Result so far: 153828.8052
Subtract 842 from 950 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 13:
1080 divided by 421 is 2 with a remainder of 238.
Write down 2 as next digit of the result. 
Result so far: 153828.80522
Subtract 842 from 1080 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

After the division, we end up with 153828.80522 and a remainder of 0.000238.
