19512659 ÷ 427 
We want to divide 19512659 by 427.

Advancing to step 1:
The number 427 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 427

Moving on to step 2:
If we divide 19 by 427, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 427

Step 3:
427 goes into 195 0 times with a remainder of 195.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 195 after subtracting 0 from 195.
Bring next digit (1) of the dividend behind the 195 and repeat the process: 1951 / 427

Going ahead to step 4:
427 goes into 1951 4 times with a remainder of 243.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1708 away from 1951, we end up with 243.
Append the next digit (2) from the dividend to 243 and continue with: 2432 / 427

Let's proceed to step 5:
427 goes into 2432 5 times with a remainder of 297.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Deduct 2135 from 2432 and we're left with 297.
Take the next digit (6) from the dividend and append it to 297, then repeat: 2976 / 427

On to step 6:
2976 divided by 427 is 6 with a remainder of 414.
Record the quotient 6 as the next digit in the result. 
Result so far: 456.0
Subtracting 2562 from 2976 leaves us with 414.
Append the next digit (5) from the dividend to 414 and continue with: 4145 / 427

Step 7:
The number 427 fits into 4145 9 times, leaving a remainder of 302.
Record the quotient 9 as the next digit in the result. 
Result so far: 4569.0
Subtracting 3843 from 4145 leaves us with 302.
Append the next digit (9) from the dividend to 302 and continue with: 3029 / 427

Going ahead to step 8:
If we divide 3029 by 427, we get 7 and a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 45697.0
Subtract 2989 from 3029 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
427 can be fit into 400 0 times, resulting in a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 45697.0
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 10:
427 can be fit into 4000 9 times, resulting in a remainder of 157.
Use 9 as the next digit of our solution. 
Result so far: 45697.09
Subtracting 3843 from 4000 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 11:
427 goes into 1570 3 times with a remainder of 289.
Use 3 as the next digit of our solution. 
Result so far: 45697.093
If we take 1281 away from 1570, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 12:
427 can be fit into 2890 6 times, resulting in a remainder of 328.
The next digit of our result is 6. 
Result so far: 45697.0936
Subtracting 2562 from 2890 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 13:
If we divide 3280 by 427, we get 7 and a remainder of 291.
The number 7 becomes the next digit in our result. 
Result so far: 45697.09367
If we take 2989 away from 3280, we end up with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Moving on to step 14:
When dividing 2910 by 427, we get 6 with a remainder of 348.
Put 6 as the next digit of the answer. 
Result so far: 45697.093676
The remainder is 348 after subtracting 2562 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 15:
427 goes into 3480 8 times with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 45697.0936768
If we subtract 3416 from 3480, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 16:
427 goes into 640 1 times with a remainder of 213.
Put 1 as the next digit of the answer. 
Result so far: 45697.09367681
Subtract 427 from 640 to 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.

The quotient of the division is 45697.09367681, and the remainder is 2.13e-07.
