20587386 ÷ 155 
Let's see how many times 155 fits into 20587386.

On to step 1:
155 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 155

Moving on to step 2:
When dividing 20 by 155, we get 0 with 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.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 155

Advancing to step 3:
155 goes into 205 1 times with a remainder of 50.
The next digit of our result is 1. 
Result so far: 1.0
If we take 155 away from 205, we end up with 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 155

Let's proceed to step 4:
If we divide 508 by 155, we get 3 and a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 465 from 508 and we're left with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 155

Let's proceed to step 5:
437 divided by 155 is 2 with a remainder of 127.
Put 2 as the next digit of the answer. 
Result so far: 132.0
If we subtract 310 from 437, we get 127.
Append the next digit (3) from the dividend to 127 and continue with: 1273 / 155

Going ahead to step 6:
155 can be fit into 1273 8 times, resulting in a remainder of 33.
The next digit of our result is 8. 
Result so far: 1328.0
Subtract 1240 from 1273 to get 33.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 155

Let's proceed to step 7:
155 goes into 338 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 13282.0
The remainder is 28 after subtracting 310 from 338.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 155

Going ahead to step 8:
If we divide 286 by 155, we get 1 and a remainder of 131.
Write down 1 as next digit of the result. 
Result so far: 132821.0
Deduct 155 from 286 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 9:
155 goes into 1310 8 times with a remainder of 70.
The next digit of our result is 8. 
Result so far: 132821.8
Subtract 1240 from 1310 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
155 can be fit into 700 4 times, resulting in a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 132821.84
Subtracting 620 from 700 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.

Step 11:
The number 155 fits into 800 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 132821.845
The remainder is 25 after subtracting 775 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
250 divided by 155 is 1 with a remainder of 95.
Record the quotient 1 as the next digit in the result. 
Result so far: 132821.8451
Subtracting 155 from 250 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 13:
155 goes into 950 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 132821.84516
Deduct 930 from 950 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.

Going ahead to step 14:
When dividing 200 by 155, we get 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 132821.845161
If we subtract 155 from 200, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 15:
When dividing 450 by 155, we get 2 with a remainder of 140.
Write down 2 as next digit of the result. 
Result so far: 132821.8451612
Deduct 310 from 450 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.

Going ahead to step 16:
155 goes into 1400 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 132821.84516129
Subtract 1395 from 1400 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 132821.84516129 and a remainder of 5e-09.
