4200 divided by 19 
We're looking to find how many times 19 goes into 4200.

Moving on to step 1:
19 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 19

Let's proceed to step 2:
If we divide 42 by 19, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 38 from 42 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 19

Going ahead to step 3:
When dividing 40 by 19, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we take 38 away from 40, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 19

Going ahead to step 4:
When dividing 20 by 19, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 221.0
The remainder is 1 after subtracting 19 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 5:
If we divide 10 by 19, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 221.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 6:
The number 19 fits into 100 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 221.05
The remainder is 5 after subtracting 95 from 100.
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:
19 can be fit into 50 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 221.052
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.

On to step 8:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 221.0526
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.

Step 9:
When dividing 60 by 19, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 221.05263
Subtracting 57 from 60 leaves us 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.

Advancing to step 10:
When dividing 30 by 19, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.052631
Deduct 19 from 30 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
110 divided by 19 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 221.0526315
If we subtract 95 from 110, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
150 divided by 19 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 221.05263157
Subtract 133 from 150 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 221.05263157 with a balance of 1.7e-08.
