83960566 ÷ 355 
Let's see how many times 355 fits into 83960566.

Moving on to step 1:
The number 355 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 355

Moving on to step 2:
If we divide 83 by 355, we get 0 and a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 355

Step 3:
839 divided by 355 is 2 with a remainder of 129.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 710 from 839 and we're left with 129.
Append the next digit (6) from the dividend to 129 and continue with: 1296 / 355

Advancing to step 4:
If we divide 1296 by 355, we get 3 and a remainder of 231.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 1065 from 1296, we get 231.
Append the next digit (0) from the dividend to 231 and continue with: 2310 / 355

Going ahead to step 5:
355 can be fit into 2310 6 times, resulting in a remainder of 180.
Put 6 as the next digit of the answer. 
Result so far: 236.0
The remainder is 180 after subtracting 2130 from 2310.
Bring next digit (5) of the dividend behind the 180 and repeat the process: 1805 / 355

Advancing to step 6:
If we divide 1805 by 355, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 2365.0
Subtracting 1775 from 1805 leaves us with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 355

Moving on to step 7:
355 can be fit into 306 0 times, resulting in a remainder of 306.
Write down 0 as next digit of the result. 
Result so far: 23650.0
If we take 0 away from 306, we end up with 306.
Include the next digit (6) from the dividend after 306, then repeat: 3066 / 355

Step 8:
If we divide 3066 by 355, we get 8 and a remainder of 226.
Put 8 as the next digit of the answer. 
Result so far: 236508.0
Subtract 2840 from 3066 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 9:
355 goes into 2260 6 times with a remainder of 130.
The next digit of our result is 6. 
Result so far: 236508.6
Deduct 2130 from 2260 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
When dividing 1300 by 355, we get 3 with a remainder of 235.
The number 3 becomes the next digit in our result. 
Result so far: 236508.63
Deduct 1065 from 1300 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 11:
The number 355 fits into 2350 6 times, leaving a remainder of 220.
The number 6 becomes the next digit in our result. 
Result so far: 236508.636
The remainder is 220 after subtracting 2130 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 12:
2200 divided by 355 is 6 with a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 236508.6366
If we take 2130 away from 2200, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 236508.6366 and a remainder of 0.0007.
