375521 ÷ 19 
We want to divide 375521 by 19.

Advancing to step 1:
19 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 19

Going ahead to step 2:
When dividing 37 by 19, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 18 after subtracting 19 from 37.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 19

Moving on to step 3:
When dividing 185 by 19, we get 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 171 from 185 to get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 19

Going ahead to step 4:
The number 19 fits into 145 7 times, leaving a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 197.0
Deduct 133 from 145 and we're left with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 19

Let's proceed to step 5:
19 goes into 122 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 1976.0
Deduct 114 from 122 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 19

Let's proceed to step 6:
19 goes into 81 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 19764.0
The remainder is 5 after subtracting 76 from 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
When dividing 50 by 19, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 19764.2
The remainder is 12 after subtracting 38 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
120 divided by 19 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 19764.26
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
If we divide 60 by 19, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 19764.263
Subtract 57 from 60 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
If we divide 30 by 19, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 19764.2631
The remainder is 11 after subtracting 19 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 11:
19 can be fit into 110 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 19764.26315
The remainder is 15 after subtracting 95 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
19 goes into 150 7 times with a remainder of 17.
The next digit of our result is 7. 
Result so far: 19764.263157
The remainder is 17 after subtracting 133 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 13:
170 divided by 19 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 19764.2631578
If we take 152 away from 170, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
180 divided by 19 is 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 19764.26315789
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 19764.26315789, with a leftover of 9e-09.
