20705643 divided by 156 
Our goal is to divide 20705643 by 156.

Step 1:
If we divide 2 by 156, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 156

On to step 2:
When dividing 20 by 156, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 156

Going ahead to step 3:
When dividing 207 by 156, we get 1 with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 156 from 207 to get 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 156

Moving on to step 4:
The number 156 fits into 510 3 times, leaving a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 468 away from 510, we end up with 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 156

Let's proceed to step 5:
425 divided by 156 is 2 with a remainder of 113.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
Subtract 312 from 425 to get 113.
Append the next digit (6) from the dividend to 113 and continue with: 1136 / 156

Step 6:
156 goes into 1136 7 times with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 1327.0
Subtracting 1092 from 1136 leaves us with 44.
Grab the next digit (4) from the dividend, add it to 44, then carry on: 444 / 156

On to step 7:
The number 156 fits into 444 2 times, leaving a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 13272.0
Subtract 312 from 444 to get 132.
Grab the next digit (3) from the dividend, add it to 132, then carry on: 1323 / 156

Moving on to step 8:
156 can be fit into 1323 8 times, resulting in a remainder of 75.
Record the quotient 8 as the next digit in the result. 
Result so far: 132728.0
Deduct 1248 from 1323 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
If we divide 750 by 156, we get 4 and a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 132728.4
If we subtract 624 from 750, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 10:
When dividing 1260 by 156, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 132728.48
Deduct 1248 from 1260 and we're left 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.

Moving on to step 11:
When dividing 120 by 156, we get 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 132728.48
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
If we divide 1200 by 156, we get 7 and a remainder of 108.
Put 7 as the next digit of the answer. 
Result so far: 132728.4807
Deduct 1092 from 1200 and we're left 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.

Advancing to step 13:
If we divide 1080 by 156, we get 6 and a remainder of 144.
The next digit of our result is 6. 
Result so far: 132728.48076
Deduct 936 from 1080 and we're left 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 14:
156 goes into 1440 9 times with a remainder of 36.
The next digit of our result is 9. 
Result so far: 132728.480769
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.

Moving on to step 15:
360 divided by 156 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 132728.4807692
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 16:
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: 132728.48076923
Subtracting 468 from 480 leaves us 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.

The final outcome is 132728.48076923, with a leftover of 1.2e-08.
