45621302 divided by 148 
We want to figure out the number of times 45621302 can be divided by 148.

On to step 1:
148 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
The remainder is 4 after subtracting 0 from 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 148

Advancing to step 2:
The number 148 fits into 45 0 times, leaving a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 148

Step 3:
148 goes into 456 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 444 from 456 to get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 148

Going ahead to step 4:
148 can be fit into 122 0 times, resulting in a remainder of 122.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we take 0 away from 122, we end up with 122.
Append the next digit (1) from the dividend to 122 and continue with: 1221 / 148

Step 5:
148 can be fit into 1221 8 times, resulting in a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 308.0
If we subtract 1184 from 1221, we get 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 148

Going ahead to step 6:
When dividing 373 by 148, we get 2 with a remainder of 77.
Record the quotient 2 as the next digit in the result. 
Result so far: 3082.0
If we take 296 away from 373, we end up with 77.
Append the next digit (0) from the dividend to 77 and continue with: 770 / 148

Step 7:
770 divided by 148 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 30825.0
Deduct 740 from 770 and we're left with 30.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 148

Moving on to step 8:
148 goes into 302 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 308252.0
If we subtract 296 from 302, we get 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 9:
60 divided by 148 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 308252.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
If we divide 600 by 148, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 308252.04
The remainder is 8 after subtracting 592 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
If we divide 80 by 148, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 308252.04
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
800 divided by 148 is 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 308252.0405
If we take 740 away from 800, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
148 can be fit into 600 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 308252.04054
Subtract 592 from 600 to 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.

On to step 14:
When dividing 80 by 148, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 308252.04054
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 15:
148 can be fit into 800 5 times, resulting in a remainder of 60.
The next digit of our result is 5. 
Result so far: 308252.0405405
Subtract 740 from 800 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 16:
The number 148 fits into 600 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 308252.04054054
The remainder is 8 after subtracting 592 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 308252.04054054 with a balance of 8e-09.
