20478245 ÷ 156 
Our goal is to divide 20478245 by 156.

On to step 1:
156 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 156

Moving on to step 2:
The number 156 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 156

Moving on to step 3:
156 goes into 204 1 times with a remainder of 48.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 156 from 204 leaves us with 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 156

Step 4:
If we divide 487 by 156, we get 3 and a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 468 from 487 to get 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 156

Moving on to step 5:
156 goes into 198 1 times with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Subtracting 156 from 198 leaves us with 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 156

Going ahead to step 6:
422 divided by 156 is 2 with a remainder of 110.
Record the quotient 2 as the next digit in the result. 
Result so far: 1312.0
Subtracting 312 from 422 leaves us with 110.
Append the next digit (4) from the dividend to 110 and continue with: 1104 / 156

Going ahead to step 7:
156 can be fit into 1104 7 times, resulting in a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 13127.0
Subtracting 1092 from 1104 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 156

Moving on to step 8:
When dividing 125 by 156, we get 0 with a remainder of 125.
Put 0 as the next digit of the answer. 
Result so far: 131270.0
The remainder is 125 after subtracting 0 from 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 9:
156 goes into 1250 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 131270.8
If we subtract 1248 from 1250, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
156 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 131270.8
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
156 goes into 200 1 times with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 131270.801
If we take 156 away from 200, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
The number 156 fits into 440 2 times, leaving a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 131270.8012
Subtracting 312 from 440 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 13:
If we divide 1280 by 156, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 131270.80128
Deduct 1248 from 1280 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
156 goes into 320 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 131270.801282
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 15:
156 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 131270.801282
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
156 goes into 800 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 131270.80128205
The remainder is 20 after subtracting 780 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 131270.80128205 with a remaining 2e-08.
