Let's divide 81380587 by 156
We want to divide 81380587 by 156.

On to step 1:
When dividing 8 by 156, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 156

Moving on to step 2:
81 divided by 156 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 156

On to step 3:
If we divide 813 by 156, we get 5 and a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 780 from 813 to get 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 156

Moving on to step 4:
156 goes into 338 2 times with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we subtract 312 from 338, we get 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 156

Going ahead to step 5:
260 divided by 156 is 1 with a remainder of 104.
Write down 1 as next digit of the result. 
Result so far: 521.0
Subtract 156 from 260 to get 104.
Append the next digit (5) from the dividend to 104 and continue with: 1045 / 156

Going ahead to step 6:
When dividing 1045 by 156, we get 6 with a remainder of 109.
The next digit of our result is 6. 
Result so far: 5216.0
If we subtract 936 from 1045, we get 109.
Grab the next digit (8) from the dividend, add it to 109, then carry on: 1098 / 156

On to step 7:
1098 divided by 156 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 52167.0
If we take 1092 away from 1098, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 156

Advancing to step 8:
156 can be fit into 67 0 times, resulting in a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 521670.0
If we subtract 0 from 67, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 9:
The number 156 fits into 670 4 times, leaving a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 521670.4
Subtracting 624 from 670 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
156 can be fit into 460 2 times, resulting in a remainder of 148.
The next digit of our result is 2. 
Result so far: 521670.42
Deduct 312 from 460 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 11:
If we divide 1480 by 156, we get 9 and a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 521670.429
If we take 1404 away from 1480, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
The number 156 fits into 760 4 times, leaving a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 521670.4294
Subtracting 624 from 760 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 13:
When dividing 1360 by 156, we get 8 with a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 521670.42948
If we subtract 1248 from 1360, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 14:
1120 divided by 156 is 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 521670.429487
Subtracting 1092 from 1120 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 15:
156 goes into 280 1 times with a remainder of 124.
Use 1 as the next digit of our solution. 
Result so far: 521670.4294871
If we take 156 away from 280, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 16:
If we divide 1240 by 156, we get 7 and a remainder of 148.
Use 7 as the next digit of our solution. 
Result so far: 521670.42948717
The remainder is 148 after subtracting 1092 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Our division results in 521670.42948717 with a remaining 1.48e-07.
