20157084 ÷ 156 
Let's see how many times 156 fits into 20157084.

Advancing to step 1:
When dividing 2 by 156, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 156

Moving on to step 2:
The number 156 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 156

Let's proceed to step 3:
201 divided by 156 is 1 with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 45 after subtracting 156 from 201.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 156

Step 4:
The number 156 fits into 455 2 times, leaving a remainder of 143.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 312 from 455 leaves us with 143.
Append the next digit (7) from the dividend to 143 and continue with: 1437 / 156

Step 5:
156 can be fit into 1437 9 times, resulting in a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Subtract 1404 from 1437 to get 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 156

Going ahead to step 6:
The number 156 fits into 330 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 1292.0
Deduct 312 from 330 and we're left with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 156

Moving on to step 7:
The number 156 fits into 188 1 times, leaving a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 12921.0
Subtracting 156 from 188 leaves us with 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 156

Let's proceed to step 8:
324 divided by 156 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 129212.0
If we take 312 away from 324, we end up with 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 9:
The number 156 fits into 120 0 times, leaving a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 129212.0
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
156 can be fit into 1200 7 times, resulting in a remainder of 108.
Write down 7 as next digit of the result. 
Result so far: 129212.07
The remainder is 108 after subtracting 1092 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 11:
1080 divided by 156 is 6 with a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 129212.076
If we take 936 away from 1080, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 12:
156 can be fit into 1440 9 times, resulting in a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 129212.0769
If we take 1404 away from 1440, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
156 goes into 360 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 129212.07692
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
The number 156 fits into 480 3 times, leaving a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 129212.076923
If we subtract 468 from 480, 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.

Step 15:
156 can be fit into 120 0 times, resulting in a remainder of 120.
The next digit of our result is 0. 
Result so far: 129212.076923
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 16:
The number 156 fits into 1200 7 times, leaving a remainder of 108.
Put 7 as the next digit of the answer. 
Result so far: 129212.07692307
Subtracting 1092 from 1200 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 129212.07692307, with a leftover of 1.08e-07.
