We look at the division of 66859899 by 356 
We're looking to find how many times 356 goes into 66859899.

Let's proceed to step 1:
356 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 356

Moving on to step 2:
When dividing 66 by 356, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 356

Let's proceed to step 3:
356 can be fit into 668 1 times, resulting in a remainder of 312.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 356 from 668 and we're left with 312.
Bring next digit (5) of the dividend behind the 312 and repeat the process: 3125 / 356

Step 4:
When dividing 3125 by 356, we get 8 with a remainder of 277.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 2848 from 3125, we get 277.
Grab the next digit (9) from the dividend, add it to 277, then carry on: 2779 / 356

Step 5:
356 goes into 2779 7 times with a remainder of 287.
Put 7 as the next digit of the answer. 
Result so far: 187.0
The remainder is 287 after subtracting 2492 from 2779.
Append the next digit (8) from the dividend to 287 and continue with: 2878 / 356

Moving on to step 6:
The number 356 fits into 2878 8 times, leaving a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 1878.0
Subtracting 2848 from 2878 leaves us with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 356

Let's proceed to step 7:
When dividing 309 by 356, we get 0 with a remainder of 309.
Put 0 as the next digit of the answer. 
Result so far: 18780.0
Deduct 0 from 309 and we're left with 309.
Include the next digit (9) from the dividend after 309, then repeat: 3099 / 356

Advancing to step 8:
When dividing 3099 by 356, we get 8 with a remainder of 251.
The next digit of our result is 8. 
Result so far: 187808.0
Subtracting 2848 from 3099 leaves us with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 9:
If we divide 2510 by 356, we get 7 and a remainder of 18.
The next digit of our result is 7. 
Result so far: 187808.7
If we take 2492 away from 2510, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
356 goes into 180 0 times with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 187808.7
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
356 goes into 1800 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 187808.705
Deduct 1780 from 1800 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
The number 356 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 187808.705
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 13:
When dividing 2000 by 356, we get 5 with a remainder of 220.
Write down 5 as next digit of the result. 
Result so far: 187808.70505
Subtracting 1780 from 2000 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 14:
The number 356 fits into 2200 6 times, leaving a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 187808.705056
If we subtract 2136 from 2200, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
640 divided by 356 is 1 with a remainder of 284.
The number 1 becomes the next digit in our result. 
Result so far: 187808.7050561
If we take 356 away from 640, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 16:
356 goes into 2840 7 times with a remainder of 348.
Use 7 as the next digit of our solution. 
Result so far: 187808.70505617
Subtracting 2492 from 2840 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

After the division, we end up with 187808.70505617 and a remainder of 3.48e-07.
