We look at the division of 213153 by 49 
We want to figure out the number of times 213153 can be divided by 49.

Going ahead to step 1:
When dividing 2 by 49, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 49

On to step 2:
49 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 49

Advancing to step 3:
The number 49 fits into 213 4 times, leaving a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 196 from 213 and we're left with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 49

Moving on to step 4:
49 can be fit into 171 3 times, resulting in a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtract 147 from 171 to get 24.
Include the next digit (5) from the dividend after 24, then repeat: 245 / 49

Moving on to step 5:
If we divide 245 by 49, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 435.0
Deduct 245 from 245 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 49

Let's proceed to step 6:
49 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 4350.0
Subtract 0 from 3 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.

Step 7:
30 divided by 49 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 4350.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
300 divided by 49 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 4350.06
If we take 294 away from 300, 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.

Let's proceed to step 9:
When dividing 60 by 49, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 4350.061
Subtracting 49 from 60 leaves us 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.

Going ahead to step 10:
The number 49 fits into 110 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 4350.0612
If we subtract 98 from 110, we 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.

Advancing to step 11:
49 can be fit into 120 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 4350.06122
Subtract 98 from 120 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 4350.06122 with a remainder of 2.2e-05.
