83987875 ÷ 349 
Our goal is to divide 83987875 by 349.

Advancing to step 1:
If we divide 8 by 349, we get 0 and 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.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 349

Going ahead to step 2:
83 divided by 349 is 0 with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 349

On to step 3:
The number 349 fits into 839 2 times, leaving a remainder of 141.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 141 after subtracting 698 from 839.
Take the next digit (8) from the dividend and append it to 141, then repeat: 1418 / 349

Advancing to step 4:
349 goes into 1418 4 times with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 1396 from 1418 leaves us with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 349

Step 5:
349 can be fit into 227 0 times, resulting in a remainder of 227.
Use 0 as the next digit of our solution. 
Result so far: 240.0
If we take 0 away from 227, we end up with 227.
Take the next digit (8) from the dividend and append it to 227, then repeat: 2278 / 349

Going ahead to step 6:
349 can be fit into 2278 6 times, resulting in a remainder of 184.
Write down 6 as next digit of the result. 
Result so far: 2406.0
Deduct 2094 from 2278 and we're left with 184.
Include the next digit (7) from the dividend after 184, then repeat: 1847 / 349

On to step 7:
349 can be fit into 1847 5 times, resulting in a remainder of 102.
The next digit of our result is 5. 
Result so far: 24065.0
Subtract 1745 from 1847 to get 102.
Include the next digit (5) from the dividend after 102, then repeat: 1025 / 349

Going ahead to step 8:
349 can be fit into 1025 2 times, resulting in a remainder of 327.
Write down 2 as next digit of the result. 
Result so far: 240652.0
If we take 698 away from 1025, we end up with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Let's proceed to step 9:
3270 divided by 349 is 9 with a remainder of 129.
Put 9 as the next digit of the answer. 
Result so far: 240652.9
The remainder is 129 after subtracting 3141 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 10:
If we divide 1290 by 349, we get 3 and a remainder of 243.
Write down 3 as next digit of the result. 
Result so far: 240652.93
If we subtract 1047 from 1290, we get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

On to step 11:
When dividing 2430 by 349, we get 6 with a remainder of 336.
The number 6 becomes the next digit in our result. 
Result so far: 240652.936
Subtract 2094 from 2430 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 12:
3360 divided by 349 is 9 with a remainder of 219.
Use 9 as the next digit of our solution. 
Result so far: 240652.9369
The remainder is 219 after subtracting 3141 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 13:
349 goes into 2190 6 times with a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 240652.93696
Subtract 2094 from 2190 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.

Moving on to step 14:
349 goes into 960 2 times with a remainder of 262.
The next digit of our result is 2. 
Result so far: 240652.936962
If we take 698 away from 960, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 15:
The number 349 fits into 2620 7 times, leaving a remainder of 177.
Write down 7 as next digit of the result. 
Result so far: 240652.9369627
If we take 2443 away from 2620, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 16:
If we divide 1770 by 349, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 240652.93696275
If we take 1745 away from 1770, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 240652.93696275, and the remainder is 2.5e-08.
