We divide 138210 by 19
We're looking to find how many times 19 goes into 138210.

On to step 1:
1 divided by 19 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 19

Step 2:
19 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 19

Advancing to step 3:
19 can be fit into 138 7 times, resulting in a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 133 away from 138, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 19

Step 4:
If we divide 52 by 19, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 72.0
If we take 38 away from 52, we end up with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 19

Let's proceed to step 5:
When dividing 141 by 19, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 727.0
If we take 133 away from 141, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 19

Moving on to step 6:
The number 19 fits into 80 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 7274.0
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.

Let's proceed to step 7:
If we divide 40 by 19, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 7274.2
The remainder is 2 after subtracting 38 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
If we divide 20 by 19, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 7274.21
Subtract 19 from 20 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
19 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7274.21
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
When dividing 100 by 19, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 7274.2105
If we subtract 95 from 100, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
The number 19 fits into 50 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 7274.21052
Subtract 38 from 50 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
19 can be fit into 120 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 7274.210526
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
If we divide 60 by 19, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 7274.2105263
Deduct 57 from 60 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
19 goes into 30 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 7274.21052631
Subtract 19 from 30 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 7274.21052631, with a leftover of 1.1e-08.
