Let's divide 20101238 by 156
We want to figure out the number of times 20101238 can be divided by 156.

Let's proceed to step 1:
156 goes into 2 0 times with 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.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 156

Let's proceed to step 2:
156 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 156

Let's proceed to step 3:
When dividing 201 by 156, we get 1 with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 156 away from 201, we end up with 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 156

Moving on to step 4:
The number 156 fits into 450 2 times, leaving a remainder of 138.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 312 from 450 and we're left with 138.
Take the next digit (1) from the dividend and append it to 138, then repeat: 1381 / 156

Moving on to step 5:
156 can be fit into 1381 8 times, resulting in a remainder of 133.
Use 8 as the next digit of our solution. 
Result so far: 128.0
If we subtract 1248 from 1381, we get 133.
Include the next digit (2) from the dividend after 133, then repeat: 1332 / 156

Going ahead to step 6:
If we divide 1332 by 156, we get 8 and a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 1288.0
The remainder is 84 after subtracting 1248 from 1332.
Take the next digit (3) from the dividend and append it to 84, then repeat: 843 / 156

Moving on to step 7:
The number 156 fits into 843 5 times, leaving a remainder of 63.
Record the quotient 5 as the next digit in the result. 
Result so far: 12885.0
If we subtract 780 from 843, we get 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 156

Moving on to step 8:
The number 156 fits into 638 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 128854.0
Deduct 624 from 638 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
When dividing 140 by 156, we get 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 128854.0
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
When dividing 1400 by 156, we get 8 with a remainder of 152.
Use 8 as the next digit of our solution. 
Result so far: 128854.08
Deduct 1248 from 1400 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 11:
If we divide 1520 by 156, we get 9 and a remainder of 116.
Use 9 as the next digit of our solution. 
Result so far: 128854.089
Subtracting 1404 from 1520 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 12:
156 goes into 1160 7 times with a remainder of 68.
Use 7 as the next digit of our solution. 
Result so far: 128854.0897
Subtracting 1092 from 1160 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
If we divide 680 by 156, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 128854.08974
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
560 divided by 156 is 3 with a remainder of 92.
Put 3 as the next digit of the answer. 
Result so far: 128854.089743
If we subtract 468 from 560, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 15:
If we divide 920 by 156, we get 5 and a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 128854.0897435
Deduct 780 from 920 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 16:
If we divide 1400 by 156, we get 8 and a remainder of 152.
The next digit of our result is 8. 
Result so far: 128854.08974358
Subtract 1248 from 1400 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Our division results in 128854.08974358 with a remaining 1.52e-07.
