Let's divide 81957597 by 423
Our goal is to divide 81957597 by 423.

Going ahead to step 1:
423 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 423

Moving on to step 2:
When dividing 81 by 423, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 423

Moving on to step 3:
The number 423 fits into 819 1 times, leaving a remainder of 396.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 396 after subtracting 423 from 819.
Take the next digit (5) from the dividend and append it to 396, then repeat: 3965 / 423

Going ahead to step 4:
If we divide 3965 by 423, we get 9 and a remainder of 158.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 3807 away from 3965, we end up with 158.
Grab the next digit (7) from the dividend, add it to 158, then carry on: 1587 / 423

Let's proceed to step 5:
423 goes into 1587 3 times with a remainder of 318.
Write down 3 as next digit of the result. 
Result so far: 193.0
The remainder is 318 after subtracting 1269 from 1587.
Grab the next digit (5) from the dividend, add it to 318, then carry on: 3185 / 423

Moving on to step 6:
If we divide 3185 by 423, we get 7 and a remainder of 224.
The next digit of our result is 7. 
Result so far: 1937.0
If we subtract 2961 from 3185, we get 224.
Fetch the next digit (9) from the dividend, attach it to 224 and continue: 2249 / 423

Let's proceed to step 7:
423 can be fit into 2249 5 times, resulting in a remainder of 134.
The number 5 becomes the next digit in our result. 
Result so far: 19375.0
Subtract 2115 from 2249 to get 134.
Include the next digit (7) from the dividend after 134, then repeat: 1347 / 423

Going ahead to step 8:
The number 423 fits into 1347 3 times, leaving a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 193753.0
Subtract 1269 from 1347 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 9:
423 can be fit into 780 1 times, resulting in a remainder of 357.
Use 1 as the next digit of our solution. 
Result so far: 193753.1
If we take 423 away from 780, we end up with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Advancing to step 10:
3570 divided by 423 is 8 with a remainder of 186.
Record the quotient 8 as the next digit in the result. 
Result so far: 193753.18
Deduct 3384 from 3570 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 11:
423 can be fit into 1860 4 times, resulting in a remainder of 168.
The next digit of our result is 4. 
Result so far: 193753.184
If we take 1692 away from 1860, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 12:
1680 divided by 423 is 3 with a remainder of 411.
The number 3 becomes the next digit in our result. 
Result so far: 193753.1843
Subtract 1269 from 1680 to get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Let's proceed to step 13:
423 can be fit into 4110 9 times, resulting in a remainder of 303.
Put 9 as the next digit of the answer. 
Result so far: 193753.18439
The remainder is 303 after subtracting 3807 from 4110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Step 14:
423 goes into 3030 7 times with a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 193753.184397
If we subtract 2961 from 3030, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 15:
423 goes into 690 1 times with a remainder of 267.
Write down 1 as next digit of the result. 
Result so far: 193753.1843971
If we take 423 away from 690, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 16:
423 can be fit into 2670 6 times, resulting in a remainder of 132.
Put 6 as the next digit of the answer. 
Result so far: 193753.18439716
Subtract 2538 from 2670 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The quotient of the division is 193753.18439716, and the remainder is 1.32e-07.
