56615878 ÷ 665 
We're looking to find how many times 665 goes into 56615878.

Moving on to step 1:
If we divide 5 by 665, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 665

On to step 2:
56 divided by 665 is 0 with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Grab the next digit (6) from the dividend, add it to 56, then carry on: 566 / 665

Let's proceed to step 3:
When dividing 566 by 665, we get 0 with a remainder of 566.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 566 leaves us with 566.
Bring next digit (1) of the dividend behind the 566 and repeat the process: 5661 / 665

Step 4:
If we divide 5661 by 665, we get 8 and a remainder of 341.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 5320 from 5661 and we're left with 341.
Fetch the next digit (5) from the dividend, attach it to 341 and continue: 3415 / 665

On to step 5:
3415 divided by 665 is 5 with a remainder of 90.
The next digit of our result is 5. 
Result so far: 85.0
Subtracting 3325 from 3415 leaves us with 90.
Take the next digit (8) from the dividend and append it to 90, then repeat: 908 / 665

Let's proceed to step 6:
665 goes into 908 1 times with a remainder of 243.
Use 1 as the next digit of our solution. 
Result so far: 851.0
The remainder is 243 after subtracting 665 from 908.
Fetch the next digit (7) from the dividend, attach it to 243 and continue: 2437 / 665

Step 7:
If we divide 2437 by 665, we get 3 and a remainder of 442.
The number 3 becomes the next digit in our result. 
Result so far: 8513.0
The remainder is 442 after subtracting 1995 from 2437.
Grab the next digit (8) from the dividend, add it to 442, then carry on: 4428 / 665

Going ahead to step 8:
4428 divided by 665 is 6 with a remainder of 438.
The next digit of our result is 6. 
Result so far: 85136.0
Deduct 3990 from 4428 and we're left with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Let's proceed to step 9:
If we divide 4380 by 665, we get 6 and a remainder of 390.
Record the quotient 6 as the next digit in the result. 
Result so far: 85136.6
Deduct 3990 from 4380 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 10:
The number 665 fits into 3900 5 times, leaving a remainder of 575.
The next digit of our result is 5. 
Result so far: 85136.65
Deduct 3325 from 3900 and we're left with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Advancing to step 11:
When dividing 5750 by 665, we get 8 with a remainder of 430.
The next digit of our result is 8. 
Result so far: 85136.658
Subtract 5320 from 5750 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 12:
665 can be fit into 4300 6 times, resulting in a remainder of 310.
The number 6 becomes the next digit in our result. 
Result so far: 85136.6586
The remainder is 310 after subtracting 3990 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 13:
The number 665 fits into 3100 4 times, leaving a remainder of 440.
The number 4 becomes the next digit in our result. 
Result so far: 85136.65864
If we subtract 2660 from 3100, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 14:
665 can be fit into 4400 6 times, resulting in a remainder of 410.
Use 6 as the next digit of our solution. 
Result so far: 85136.658646
The remainder is 410 after subtracting 3990 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 15:
665 goes into 4100 6 times with a remainder of 110.
The number 6 becomes the next digit in our result. 
Result so far: 85136.6586466
If we subtract 3990 from 4100, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final result is 85136.6586466 with a remainder of 1.1e-06.
