52131511 divided by 423 
We want to divide 52131511 by 423.

Advancing to step 1:
423 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 423

Going ahead to step 2:
If we divide 52 by 423, we get 0 and a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Grab the next digit (1) from the dividend, add it to 52, then carry on: 521 / 423

Moving on to step 3:
If we divide 521 by 423, we get 1 and a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 98 after subtracting 423 from 521.
Fetch the next digit (3) from the dividend, attach it to 98 and continue: 983 / 423

Going ahead to step 4:
423 can be fit into 983 2 times, resulting in a remainder of 137.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 846 from 983 to get 137.
Append the next digit (1) from the dividend to 137 and continue with: 1371 / 423

Step 5:
When dividing 1371 by 423, we get 3 with a remainder of 102.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
If we take 1269 away from 1371, we end up with 102.
Fetch the next digit (5) from the dividend, attach it to 102 and continue: 1025 / 423

Let's proceed to step 6:
423 can be fit into 1025 2 times, resulting in a remainder of 179.
Put 2 as the next digit of the answer. 
Result so far: 1232.0
The remainder is 179 after subtracting 846 from 1025.
Take the next digit (1) from the dividend and append it to 179, then repeat: 1791 / 423

On to step 7:
If we divide 1791 by 423, we get 4 and a remainder of 99.
The number 4 becomes the next digit in our result. 
Result so far: 12324.0
If we take 1692 away from 1791, we end up with 99.
Append the next digit (1) from the dividend to 99 and continue with: 991 / 423

Let's proceed to step 8:
If we divide 991 by 423, we get 2 and a remainder of 145.
The number 2 becomes the next digit in our result. 
Result so far: 123242.0
Subtract 846 from 991 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 9:
If we divide 1450 by 423, we get 3 and a remainder of 181.
Write down 3 as next digit of the result. 
Result so far: 123242.3
If we subtract 1269 from 1450, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 10:
The number 423 fits into 1810 4 times, leaving a remainder of 118.
The next digit of our result is 4. 
Result so far: 123242.34
The remainder is 118 after subtracting 1692 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 11:
The number 423 fits into 1180 2 times, leaving a remainder of 334.
The next digit of our result is 2. 
Result so far: 123242.342
Subtract 846 from 1180 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 12:
3340 divided by 423 is 7 with a remainder of 379.
The number 7 becomes the next digit in our result. 
Result so far: 123242.3427
Deduct 2961 from 3340 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Moving on to step 13:
If we divide 3790 by 423, we get 8 and a remainder of 406.
The next digit of our result is 8. 
Result so far: 123242.34278
The remainder is 406 after subtracting 3384 from 3790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 14:
4060 divided by 423 is 9 with a remainder of 253.
The number 9 becomes the next digit in our result. 
Result so far: 123242.342789
Deduct 3807 from 4060 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 15:
423 can be fit into 2530 5 times, resulting in a remainder of 415.
Record the quotient 5 as the next digit in the result. 
Result so far: 123242.3427895
The remainder is 415 after subtracting 2115 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 16:
423 goes into 4150 9 times with a remainder of 343.
The number 9 becomes the next digit in our result. 
Result so far: 123242.34278959
Subtract 3807 from 4150 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

The quotient of the division is 123242.34278959, and the remainder is 3.43e-07.
