53000342 divided by 149 
We want to figure out the number of times 53000342 can be divided by 149.

Going ahead to step 1:
The number 149 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 149

Let's proceed to step 2:
149 can be fit into 53 0 times, resulting in a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Include the next digit (0) from the dividend after 53, then repeat: 530 / 149

Moving on to step 3:
When dividing 530 by 149, we get 3 with a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 83 after subtracting 447 from 530.
Append the next digit (0) from the dividend to 83 and continue with: 830 / 149

Let's proceed to step 4:
149 goes into 830 5 times with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 35.0
The remainder is 85 after subtracting 745 from 830.
Bring next digit (0) of the dividend behind the 85 and repeat the process: 850 / 149

Advancing to step 5:
149 can be fit into 850 5 times, resulting in a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 355.0
If we subtract 745 from 850, we get 105.
Bring next digit (3) of the dividend behind the 105 and repeat the process: 1053 / 149

Let's proceed to step 6:
1053 divided by 149 is 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 3557.0
If we subtract 1043 from 1053, we get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 149

Let's proceed to step 7:
If we divide 104 by 149, we get 0 and a remainder of 104.
Put 0 as the next digit of the answer. 
Result so far: 35570.0
Subtracting 0 from 104 leaves us with 104.
Take the next digit (2) from the dividend and append it to 104, then repeat: 1042 / 149

Moving on to step 8:
If we divide 1042 by 149, we get 6 and a remainder of 148.
The number 6 becomes the next digit in our result. 
Result so far: 355706.0
If we take 894 away from 1042, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 9:
When dividing 1480 by 149, we get 9 with a remainder of 139.
Write down 9 as next digit of the result. 
Result so far: 355706.9
If we take 1341 away from 1480, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 10:
1390 divided by 149 is 9 with a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 355706.99
Deduct 1341 from 1390 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The quotient of the division is 355706.99, and the remainder is 0.049.
