81738189 ÷ 349 
Our goal is to divide 81738189 by 349.

Let's proceed to step 1:
When dividing 8 by 349, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 349

Advancing to step 2:
If we divide 81 by 349, we get 0 and a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (7) of the dividend behind the 81 and repeat the process: 817 / 349

Step 3:
If we divide 817 by 349, we get 2 and a remainder of 119.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 119 after subtracting 698 from 817.
Take the next digit (3) from the dividend and append it to 119, then repeat: 1193 / 349

Moving on to step 4:
If we divide 1193 by 349, we get 3 and a remainder of 146.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 1047 from 1193, we get 146.
Append the next digit (8) from the dividend to 146 and continue with: 1468 / 349

On to step 5:
1468 divided by 349 is 4 with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 234.0
Subtract 1396 from 1468 to get 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 349

Going ahead to step 6:
721 divided by 349 is 2 with a remainder of 23.
The next digit of our result is 2. 
Result so far: 2342.0
Subtract 698 from 721 to get 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 349

Step 7:
The number 349 fits into 238 0 times, leaving a remainder of 238.
The next digit of our result is 0. 
Result so far: 23420.0
If we subtract 0 from 238, we get 238.
Take the next digit (9) from the dividend and append it to 238, then repeat: 2389 / 349

Going ahead to step 8:
The number 349 fits into 2389 6 times, leaving a remainder of 295.
The next digit of our result is 6. 
Result so far: 234206.0
Subtracting 2094 from 2389 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 9:
349 goes into 2950 8 times with a remainder of 158.
The next digit of our result is 8. 
Result so far: 234206.8
Subtracting 2792 from 2950 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 10:
When dividing 1580 by 349, we get 4 with a remainder of 184.
Write down 4 as next digit of the result. 
Result so far: 234206.84
Subtracting 1396 from 1580 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 11:
349 goes into 1840 5 times with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 234206.845
Subtracting 1745 from 1840 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 12:
The number 349 fits into 950 2 times, leaving a remainder of 252.
The next digit of our result is 2. 
Result so far: 234206.8452
Subtracting 698 from 950 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 13:
When dividing 2520 by 349, we get 7 with a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 234206.84527
Deduct 2443 from 2520 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 14:
770 divided by 349 is 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 234206.845272
The remainder is 72 after subtracting 698 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 15:
If we divide 720 by 349, we get 2 and a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 234206.8452722
The remainder is 22 after subtracting 698 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 234206.8452722, and the remainder is 2.2e-07.
