We look at the division of 83721768 by 243 
Our goal is to divide 83721768 by 243.

Going ahead to step 1:
When dividing 8 by 243, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 243

Advancing to step 2:
83 divided by 243 is 0 with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Take the next digit (7) from the dividend and append it to 83, then repeat: 837 / 243

Advancing to step 3:
If we divide 837 by 243, we get 3 and a remainder of 108.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 729 from 837 and we're left with 108.
Fetch the next digit (2) from the dividend, attach it to 108 and continue: 1082 / 243

On to step 4:
1082 divided by 243 is 4 with a remainder of 110.
Use 4 as the next digit of our solution. 
Result so far: 34.0
The remainder is 110 after subtracting 972 from 1082.
Take the next digit (1) from the dividend and append it to 110, then repeat: 1101 / 243

Step 5:
243 can be fit into 1101 4 times, resulting in a remainder of 129.
Use 4 as the next digit of our solution. 
Result so far: 344.0
Deduct 972 from 1101 and we're left with 129.
Bring next digit (7) of the dividend behind the 129 and repeat the process: 1297 / 243

On to step 6:
243 can be fit into 1297 5 times, resulting in a remainder of 82.
The number 5 becomes the next digit in our result. 
Result so far: 3445.0
If we take 1215 away from 1297, we end up with 82.
Append the next digit (6) from the dividend to 82 and continue with: 826 / 243

Step 7:
243 goes into 826 3 times with a remainder of 97.
Use 3 as the next digit of our solution. 
Result so far: 34453.0
If we subtract 729 from 826, we get 97.
Append the next digit (8) from the dividend to 97 and continue with: 978 / 243

Step 8:
The number 243 fits into 978 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 344534.0
Subtract 972 from 978 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
If we divide 60 by 243, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 344534.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
If we divide 600 by 243, we get 2 and a remainder of 114.
Put 2 as the next digit of the answer. 
Result so far: 344534.02
Subtract 486 from 600 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 11:
The number 243 fits into 1140 4 times, leaving a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 344534.024
The remainder is 168 after subtracting 972 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 12:
243 goes into 1680 6 times with a remainder of 222.
Write down 6 as next digit of the result. 
Result so far: 344534.0246
Deduct 1458 from 1680 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 13:
243 can be fit into 2220 9 times, resulting in a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 344534.02469
If we take 2187 away from 2220, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 14:
When dividing 330 by 243, we get 1 with a remainder of 87.
The next digit of our result is 1. 
Result so far: 344534.024691
The remainder is 87 after subtracting 243 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 15:
When dividing 870 by 243, we get 3 with a remainder of 141.
Record the quotient 3 as the next digit in the result. 
Result so far: 344534.0246913
Subtracting 729 from 870 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 16:
243 goes into 1410 5 times with a remainder of 195.
The number 5 becomes the next digit in our result. 
Result so far: 344534.02469135
Deduct 1215 from 1410 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

The final result is 344534.02469135 with a remainder of 1.95e-07.
