We're dividing 64869950 by 486 
We want to figure out the number of times 64869950 can be divided by 486.

Let's proceed to step 1:
When dividing 6 by 486, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 486

Moving on to step 2:
64 divided by 486 is 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 486

Going ahead to step 3:
648 divided by 486 is 1 with a remainder of 162.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 486 away from 648, we end up with 162.
Fetch the next digit (6) from the dividend, attach it to 162 and continue: 1626 / 486

On to step 4:
The number 486 fits into 1626 3 times, leaving a remainder of 168.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1458 away from 1626, we end up with 168.
Bring next digit (9) of the dividend behind the 168 and repeat the process: 1689 / 486

Step 5:
486 can be fit into 1689 3 times, resulting in a remainder of 231.
The next digit of our result is 3. 
Result so far: 133.0
If we take 1458 away from 1689, we end up with 231.
Append the next digit (9) from the dividend to 231 and continue with: 2319 / 486

On to step 6:
If we divide 2319 by 486, we get 4 and a remainder of 375.
Record the quotient 4 as the next digit in the result. 
Result so far: 1334.0
Subtract 1944 from 2319 to get 375.
Grab the next digit (5) from the dividend, add it to 375, then carry on: 3755 / 486

Let's proceed to step 7:
The number 486 fits into 3755 7 times, leaving a remainder of 353.
The number 7 becomes the next digit in our result. 
Result so far: 13347.0
If we take 3402 away from 3755, we end up with 353.
Grab the next digit (0) from the dividend, add it to 353, then carry on: 3530 / 486

On to step 8:
If we divide 3530 by 486, we get 7 and a remainder of 128.
Use 7 as the next digit of our solution. 
Result so far: 133477.0
Subtract 3402 from 3530 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 9:
When dividing 1280 by 486, we get 2 with a remainder of 308.
The next digit of our result is 2. 
Result so far: 133477.2
If we take 972 away from 1280, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 10:
If we divide 3080 by 486, we get 6 and a remainder of 164.
Record the quotient 6 as the next digit in the result. 
Result so far: 133477.26
If we take 2916 away from 3080, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 11:
486 goes into 1640 3 times with a remainder of 182.
Record the quotient 3 as the next digit in the result. 
Result so far: 133477.263
Subtracting 1458 from 1640 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 12:
The number 486 fits into 1820 3 times, leaving a remainder of 362.
The next digit of our result is 3. 
Result so far: 133477.2633
If we subtract 1458 from 1820, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

The final outcome is 133477.2633, with a leftover of 0.00362.
