Let's divide 16780951 by 423
We want to divide 16780951 by 423.

Moving on to step 1:
When dividing 1 by 423, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 423

Advancing to step 2:
If we divide 16 by 423, we get 0 and a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 423

Let's proceed to step 3:
The number 423 fits into 167 0 times, leaving a remainder of 167.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 167 after subtracting 0 from 167.
Grab the next digit (8) from the dividend, add it to 167, then carry on: 1678 / 423

Going ahead to step 4:
423 goes into 1678 3 times with a remainder of 409.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1269 from 1678 leaves us with 409.
Include the next digit (0) from the dividend after 409, then repeat: 4090 / 423

Step 5:
423 goes into 4090 9 times with a remainder of 283.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 3807 from 4090 to get 283.
Include the next digit (9) from the dividend after 283, then repeat: 2839 / 423

On to step 6:
The number 423 fits into 2839 6 times, leaving a remainder of 301.
The number 6 becomes the next digit in our result. 
Result so far: 396.0
Subtracting 2538 from 2839 leaves us with 301.
Bring next digit (5) of the dividend behind the 301 and repeat the process: 3015 / 423

Moving on to step 7:
If we divide 3015 by 423, we get 7 and a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 3967.0
Deduct 2961 from 3015 and we're left with 54.
Fetch the next digit (1) from the dividend, attach it to 54 and continue: 541 / 423

Going ahead to step 8:
When dividing 541 by 423, we get 1 with a remainder of 118.
The next digit of our result is 1. 
Result so far: 39671.0
Subtract 423 from 541 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 9:
When dividing 1180 by 423, we get 2 with a remainder of 334.
The number 2 becomes the next digit in our result. 
Result so far: 39671.2
If we subtract 846 from 1180, we 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.

Step 10:
3340 divided by 423 is 7 with a remainder of 379.
Put 7 as the next digit of the answer. 
Result so far: 39671.27
If we subtract 2961 from 3340, we get 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 11:
The number 423 fits into 3790 8 times, leaving a remainder of 406.
The next digit of our result is 8. 
Result so far: 39671.278
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.

On to step 12:
When dividing 4060 by 423, we get 9 with a remainder of 253.
Put 9 as the next digit of the answer. 
Result so far: 39671.2789
Subtracting 3807 from 4060 leaves us 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 13:
The number 423 fits into 2530 5 times, leaving a remainder of 415.
Write down 5 as next digit of the result. 
Result so far: 39671.27895
Deduct 2115 from 2530 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Going ahead to step 14:
423 can be fit into 4150 9 times, resulting in a remainder of 343.
Put 9 as the next digit of the answer. 
Result so far: 39671.278959
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.

Moving on to step 15:
When dividing 3430 by 423, we get 8 with a remainder of 46.
The next digit of our result is 8. 
Result so far: 39671.2789598
If we subtract 3384 from 3430, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 16:
423 goes into 460 1 times with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 39671.27895981
The remainder is 37 after subtracting 423 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The quotient of the division is 39671.27895981, and the remainder is 3.7e-08.
