We divide 6678405 by 561
We want to figure out the number of times 6678405 can be divided by 561.

On to step 1:
6 divided by 561 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 561

Advancing to step 2:
561 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 561

Moving on to step 3:
667 divided by 561 is 1 with a remainder of 106.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 561 from 667 leaves us with 106.
Take the next digit (8) from the dividend and append it to 106, then repeat: 1068 / 561

Moving on to step 4:
561 goes into 1068 1 times with a remainder of 507.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 561 from 1068 and we're left with 507.
Fetch the next digit (4) from the dividend, attach it to 507 and continue: 5074 / 561

Let's proceed to step 5:
The number 561 fits into 5074 9 times, leaving a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we subtract 5049 from 5074, we get 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 561

Moving on to step 6:
When dividing 250 by 561, we get 0 with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 1190.0
If we subtract 0 from 250, we get 250.
Grab the next digit (5) from the dividend, add it to 250, then carry on: 2505 / 561

Going ahead to step 7:
When dividing 2505 by 561, we get 4 with a remainder of 261.
The number 4 becomes the next digit in our result. 
Result so far: 11904.0
Subtracting 2244 from 2505 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Let's proceed to step 8:
If we divide 2610 by 561, we get 4 and a remainder of 366.
The next digit of our result is 4. 
Result so far: 11904.4
The remainder is 366 after subtracting 2244 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 9:
3660 divided by 561 is 6 with a remainder of 294.
Write down 6 as next digit of the result. 
Result so far: 11904.46
Deduct 3366 from 3660 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 10:
561 can be fit into 2940 5 times, resulting in a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 11904.465
If we take 2805 away from 2940, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 11:
561 goes into 1350 2 times with a remainder of 228.
Write down 2 as next digit of the result. 
Result so far: 11904.4652
If we take 1122 away from 1350, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 12:
2280 divided by 561 is 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 11904.46524
Subtracting 2244 from 2280 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
561 can be fit into 360 0 times, resulting in a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 11904.46524
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 14:
3600 divided by 561 is 6 with a remainder of 234.
Use 6 as the next digit of our solution. 
Result so far: 11904.4652406
The remainder is 234 after subtracting 3366 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 15:
When dividing 2340 by 561, we get 4 with a remainder of 96.
The next digit of our result is 4. 
Result so far: 11904.46524064
Subtract 2244 from 2340 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 11904.46524064 and a remainder of 9.6e-08.
