We divide 34361819 by 866
We want to divide 34361819 by 866.

Moving on to step 1:
The number 866 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 866

Let's proceed to step 2:
866 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 866

Going ahead to step 3:
If we divide 343 by 866, we get 0 and a remainder of 343.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 343 leaves us with 343.
Fetch the next digit (6) from the dividend, attach it to 343 and continue: 3436 / 866

Step 4:
3436 divided by 866 is 3 with a remainder of 838.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 2598 away from 3436, we end up with 838.
Include the next digit (1) from the dividend after 838, then repeat: 8381 / 866

Advancing to step 5:
The number 866 fits into 8381 9 times, leaving a remainder of 587.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 7794 from 8381, we get 587.
Fetch the next digit (8) from the dividend, attach it to 587 and continue: 5878 / 866

Advancing to step 6:
When dividing 5878 by 866, we get 6 with a remainder of 682.
Write down 6 as next digit of the result. 
Result so far: 396.0
If we take 5196 away from 5878, we end up with 682.
Bring next digit (1) of the dividend behind the 682 and repeat the process: 6821 / 866

Moving on to step 7:
866 can be fit into 6821 7 times, resulting in a remainder of 759.
Use 7 as the next digit of our solution. 
Result so far: 3967.0
Deduct 6062 from 6821 and we're left with 759.
Grab the next digit (9) from the dividend, add it to 759, then carry on: 7599 / 866

Advancing to step 8:
866 goes into 7599 8 times with a remainder of 671.
Put 8 as the next digit of the answer. 
Result so far: 39678.0
Deduct 6928 from 7599 and we're left with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Moving on to step 9:
The number 866 fits into 6710 7 times, leaving a remainder of 648.
Write down 7 as next digit of the result. 
Result so far: 39678.7
The remainder is 648 after subtracting 6062 from 6710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Moving on to step 10:
6480 divided by 866 is 7 with a remainder of 418.
Use 7 as the next digit of our solution. 
Result so far: 39678.77
Subtract 6062 from 6480 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

The final outcome is 39678.77, with a leftover of 0.418.
