Let's divide 42212850 by 661
Let's see how many times 661 fits into 42212850.

Step 1:
If we divide 4 by 661, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 661

Let's proceed to step 2:
If we divide 42 by 661, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 661

On to step 3:
When dividing 422 by 661, we get 0 with a remainder of 422.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 422 after subtracting 0 from 422.
Take the next digit (1) from the dividend and append it to 422, then repeat: 4221 / 661

On to step 4:
4221 divided by 661 is 6 with a remainder of 255.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 255 after subtracting 3966 from 4221.
Bring next digit (2) of the dividend behind the 255 and repeat the process: 2552 / 661

Moving on to step 5:
If we divide 2552 by 661, we get 3 and a remainder of 569.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
The remainder is 569 after subtracting 1983 from 2552.
Append the next digit (8) from the dividend to 569 and continue with: 5698 / 661

Step 6:
5698 divided by 661 is 8 with a remainder of 410.
Put 8 as the next digit of the answer. 
Result so far: 638.0
If we subtract 5288 from 5698, we get 410.
Append the next digit (5) from the dividend to 410 and continue with: 4105 / 661

Let's proceed to step 7:
When dividing 4105 by 661, we get 6 with a remainder of 139.
Record the quotient 6 as the next digit in the result. 
Result so far: 6386.0
If we take 3966 away from 4105, we end up with 139.
Append the next digit (0) from the dividend to 139 and continue with: 1390 / 661

Let's proceed to step 8:
1390 divided by 661 is 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 63862.0
If we subtract 1322 from 1390, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 9:
680 divided by 661 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 63862.1
Subtract 661 from 680 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
661 can be fit into 190 0 times, resulting in a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 63862.1
If we take 0 away from 190, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 11:
When dividing 1900 by 661, we get 2 with a remainder of 578.
Put 2 as the next digit of the answer. 
Result so far: 63862.102
Subtract 1322 from 1900 to get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Moving on to step 12:
If we divide 5780 by 661, we get 8 and a remainder of 492.
The next digit of our result is 8. 
Result so far: 63862.1028
Subtract 5288 from 5780 to get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 13:
When dividing 4920 by 661, we get 7 with a remainder of 293.
Put 7 as the next digit of the answer. 
Result so far: 63862.10287
If we take 4627 away from 4920, we end up with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Going ahead to step 14:
When dividing 2930 by 661, we get 4 with a remainder of 286.
Use 4 as the next digit of our solution. 
Result so far: 63862.102874
If we take 2644 away from 2930, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 15:
661 can be fit into 2860 4 times, resulting in a remainder of 216.
Use 4 as the next digit of our solution. 
Result so far: 63862.1028744
Subtract 2644 from 2860 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The final result is 63862.1028744 with a remainder of 2.16e-06.
