53786679 ÷ 423 
Our goal is to divide 53786679 by 423.

Moving on to step 1:
When dividing 5 by 423, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 423

Advancing to step 2:
The number 423 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 423

On to step 3:
537 divided by 423 is 1 with a remainder of 114.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 423 from 537, we get 114.
Include the next digit (8) from the dividend after 114, then repeat: 1148 / 423

Let's proceed to step 4:
423 can be fit into 1148 2 times, resulting in a remainder of 302.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 846 from 1148 leaves us with 302.
Take the next digit (6) from the dividend and append it to 302, then repeat: 3026 / 423

Advancing to step 5:
423 goes into 3026 7 times with a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Deduct 2961 from 3026 and we're left with 65.
Append the next digit (6) from the dividend to 65 and continue with: 656 / 423

Advancing to step 6:
656 divided by 423 is 1 with a remainder of 233.
The next digit of our result is 1. 
Result so far: 1271.0
If we subtract 423 from 656, we get 233.
Append the next digit (7) from the dividend to 233 and continue with: 2337 / 423

Going ahead to step 7:
When dividing 2337 by 423, we get 5 with a remainder of 222.
The number 5 becomes the next digit in our result. 
Result so far: 12715.0
If we subtract 2115 from 2337, we get 222.
Include the next digit (9) from the dividend after 222, then repeat: 2229 / 423

Let's proceed to step 8:
2229 divided by 423 is 5 with a remainder of 114.
The next digit of our result is 5. 
Result so far: 127155.0
Subtract 2115 from 2229 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.

Let's proceed to step 9:
The number 423 fits into 1140 2 times, leaving a remainder of 294.
The number 2 becomes the next digit in our result. 
Result so far: 127155.2
Deduct 846 from 1140 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 10:
423 can be fit into 2940 6 times, resulting in a remainder of 402.
Use 6 as the next digit of our solution. 
Result so far: 127155.26
The remainder is 402 after subtracting 2538 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 11:
The number 423 fits into 4020 9 times, leaving a remainder of 213.
Record the quotient 9 as the next digit in the result. 
Result so far: 127155.269
If we subtract 3807 from 4020, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 12:
If we divide 2130 by 423, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 127155.2695
Subtracting 2115 from 2130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
423 goes into 150 0 times with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 127155.2695
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 14:
423 goes into 1500 3 times with a remainder of 231.
Record the quotient 3 as the next digit in the result. 
Result so far: 127155.269503
Deduct 1269 from 1500 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 15:
When dividing 2310 by 423, we get 5 with a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 127155.2695035
If we subtract 2115 from 2310, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 16:
1950 divided by 423 is 4 with a remainder of 258.
The next digit of our result is 4. 
Result so far: 127155.26950354
If we take 1692 away from 1950, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

After the division, we end up with 127155.26950354 and a remainder of 2.58e-07.
