357521 divided by 19 
Our goal is to divide 357521 by 19.

Moving on to step 1:
When dividing 3 by 19, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 19

Step 2:
19 goes into 35 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 19 from 35 to get 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 19

Going ahead to step 3:
19 can be fit into 167 8 times, resulting in a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 152 from 167 leaves us with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 19

Going ahead to step 4:
If we divide 155 by 19, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 188.0
Deduct 152 from 155 and we're left with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 19

Step 5:
The number 19 fits into 32 1 times, leaving a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1881.0
The remainder is 13 after subtracting 19 from 32.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 19

Going ahead to step 6:
19 can be fit into 131 6 times, resulting in a remainder of 17.
The next digit of our result is 6. 
Result so far: 18816.0
The remainder is 17 after subtracting 114 from 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
19 can be fit into 170 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 18816.8
If we subtract 152 from 170, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
19 can be fit into 180 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 18816.89
Deduct 171 from 180 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
19 goes into 90 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 18816.894
The remainder is 14 after subtracting 76 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
19 can be fit into 140 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 18816.8947
The remainder is 7 after subtracting 133 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 18816.89473
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
When dividing 130 by 19, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 18816.894736
The remainder is 16 after subtracting 114 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
160 divided by 19 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 18816.8947368
If we subtract 152 from 160, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
19 can be fit into 80 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 18816.89473684
Deduct 76 from 80 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 18816.89473684, with a leftover of 4e-09.
