We look at the division of 63665381 by 155 
Let's see how many times 155 fits into 63665381.

Advancing to step 1:
155 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 155

Step 2:
The number 155 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 155

On to step 3:
155 goes into 636 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 16 after subtracting 620 from 636.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 155

Advancing to step 4:
166 divided by 155 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we subtract 155 from 166, we get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 155

Advancing to step 5:
If we divide 115 by 155, we get 0 and a remainder of 115.
Put 0 as the next digit of the answer. 
Result so far: 410.0
Subtracting 0 from 115 leaves us with 115.
Take the next digit (3) from the dividend and append it to 115, then repeat: 1153 / 155

Step 6:
155 can be fit into 1153 7 times, resulting in a remainder of 68.
Write down 7 as next digit of the result. 
Result so far: 4107.0
Deduct 1085 from 1153 and we're left with 68.
Grab the next digit (8) from the dividend, add it to 68, then carry on: 688 / 155

Let's proceed to step 7:
155 goes into 688 4 times with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 41074.0
If we take 620 away from 688, we end up with 68.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 155

Advancing to step 8:
When dividing 681 by 155, we get 4 with a remainder of 61.
Use 4 as the next digit of our solution. 
Result so far: 410744.0
The remainder is 61 after subtracting 620 from 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
155 goes into 610 3 times with a remainder of 145.
The number 3 becomes the next digit in our result. 
Result so far: 410744.3
Deduct 465 from 610 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 10:
The number 155 fits into 1450 9 times, leaving a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 410744.39
Subtracting 1395 from 1450 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 11:
155 can be fit into 550 3 times, resulting in a remainder of 85.
The number 3 becomes the next digit in our result. 
Result so far: 410744.393
Deduct 465 from 550 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 12:
If we divide 850 by 155, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 410744.3935
If we take 775 away from 850, we end up 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.

Step 13:
750 divided by 155 is 4 with a remainder of 130.
Record the quotient 4 as the next digit in the result. 
Result so far: 410744.39354
Deduct 620 from 750 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 14:
If we divide 1300 by 155, we get 8 and a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 410744.393548
If we take 1240 away from 1300, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 15:
If we divide 600 by 155, we get 3 and a remainder of 135.
The number 3 becomes the next digit in our result. 
Result so far: 410744.3935483
Subtract 465 from 600 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 16:
When dividing 1350 by 155, we get 8 with a remainder of 110.
The next digit of our result is 8. 
Result so far: 410744.39354838
Subtract 1240 from 1350 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 410744.39354838 and a remainder of 1.1e-07.
