61016146 divided by 866 
We're looking to find how many times 866 goes into 61016146.

Step 1:
866 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 866

Step 2:
The number 866 fits into 61 0 times, leaving a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Grab the next digit (0) from the dividend, add it to 61, then carry on: 610 / 866

Moving on to step 3:
If we divide 610 by 866, we get 0 and a remainder of 610.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 610, we end up with 610.
Include the next digit (1) from the dividend after 610, then repeat: 6101 / 866

Step 4:
866 goes into 6101 7 times with a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 39 after subtracting 6062 from 6101.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 866

Going ahead to step 5:
If we divide 396 by 866, we get 0 and a remainder of 396.
Write down 0 as next digit of the result. 
Result so far: 70.0
If we take 0 away from 396, we end up with 396.
Take the next digit (1) from the dividend and append it to 396, then repeat: 3961 / 866

Let's proceed to step 6:
If we divide 3961 by 866, we get 4 and a remainder of 497.
The next digit of our result is 4. 
Result so far: 704.0
Deduct 3464 from 3961 and we're left with 497.
Bring next digit (4) of the dividend behind the 497 and repeat the process: 4974 / 866

Let's proceed to step 7:
If we divide 4974 by 866, we get 5 and a remainder of 644.
Use 5 as the next digit of our solution. 
Result so far: 7045.0
The remainder is 644 after subtracting 4330 from 4974.
Fetch the next digit (6) from the dividend, attach it to 644 and continue: 6446 / 866

Step 8:
When dividing 6446 by 866, we get 7 with a remainder of 384.
Write down 7 as next digit of the result. 
Result so far: 70457.0
Subtract 6062 from 6446 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 9:
3840 divided by 866 is 4 with a remainder of 376.
Put 4 as the next digit of the answer. 
Result so far: 70457.4
Deduct 3464 from 3840 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 10:
866 can be fit into 3760 4 times, resulting in a remainder of 296.
Use 4 as the next digit of our solution. 
Result so far: 70457.44
Subtract 3464 from 3760 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Our division results in 70457.44 with a remaining 0.296.
