20535720 ÷ 148 
We want to figure out the number of times 20535720 can be divided by 148.

Advancing to step 1:
148 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 148

Advancing to step 2:
148 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 148

Moving on to step 3:
If we divide 205 by 148, we get 1 and a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 148 from 205 leaves us with 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 148

Let's proceed to step 4:
When dividing 573 by 148, we get 3 with a remainder of 129.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 444 from 573 to get 129.
Append the next digit (5) from the dividend to 129 and continue with: 1295 / 148

Let's proceed to step 5:
148 goes into 1295 8 times with a remainder of 111.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
If we take 1184 away from 1295, we end up with 111.
Append the next digit (7) from the dividend to 111 and continue with: 1117 / 148

Going ahead to step 6:
The number 148 fits into 1117 7 times, leaving a remainder of 81.
Put 7 as the next digit of the answer. 
Result so far: 1387.0
Deduct 1036 from 1117 and we're left with 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 148

Advancing to step 7:
812 divided by 148 is 5 with a remainder of 72.
Record the quotient 5 as the next digit in the result. 
Result so far: 13875.0
Deduct 740 from 812 and we're left with 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 148

On to step 8:
The number 148 fits into 720 4 times, leaving a remainder of 128.
The next digit of our result is 4. 
Result so far: 138754.0
If we subtract 592 from 720, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 9:
148 goes into 1280 8 times with a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 138754.8
Subtract 1184 from 1280 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 10:
148 can be fit into 960 6 times, resulting in a remainder of 72.
The next digit of our result is 6. 
Result so far: 138754.86
If we take 888 away from 960, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
148 can be fit into 720 4 times, resulting in a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 138754.864
The remainder is 128 after subtracting 592 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 12:
The number 148 fits into 1280 8 times, leaving a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 138754.8648
If we take 1184 away from 1280, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 13:
148 can be fit into 960 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 138754.86486
If we subtract 888 from 960, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 14:
When dividing 720 by 148, we get 4 with a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 138754.864864
If we subtract 592 from 720, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 15:
If we divide 1280 by 148, we get 8 and a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 138754.8648648
If we take 1184 away from 1280, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 16:
The number 148 fits into 960 6 times, leaving a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 138754.86486486
If we subtract 888 from 960, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 138754.86486486 and a remainder of 7.2e-08.
