We're dividing 85103257 by 155 
Our goal is to divide 85103257 by 155.

Moving on to step 1:
If we divide 8 by 155, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 155

Moving on to step 2:
When dividing 85 by 155, we get 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Append the next digit (1) from the dividend to 85 and continue with: 851 / 155

Let's proceed to step 3:
155 can be fit into 851 5 times, resulting in a remainder of 76.
The next digit of our result is 5. 
Result so far: 5.0
If we take 775 away from 851, we end up with 76.
Bring next digit (0) of the dividend behind the 76 and repeat the process: 760 / 155

Going ahead to step 4:
760 divided by 155 is 4 with a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Deduct 620 from 760 and we're left with 140.
Include the next digit (3) from the dividend after 140, then repeat: 1403 / 155

Advancing to step 5:
155 can be fit into 1403 9 times, resulting in a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 549.0
Subtracting 1395 from 1403 leaves us with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 155

Step 6:
82 divided by 155 is 0 with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 5490.0
If we take 0 away from 82, we end up with 82.
Grab the next digit (5) from the dividend, add it to 82, then carry on: 825 / 155

On to step 7:
155 goes into 825 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 54905.0
Deduct 775 from 825 and we're left with 50.
Include the next digit (7) from the dividend after 50, then repeat: 507 / 155

Let's proceed to step 8:
The number 155 fits into 507 3 times, leaving a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 549053.0
The remainder is 42 after subtracting 465 from 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
155 goes into 420 2 times with a remainder of 110.
Write down 2 as next digit of the result. 
Result so far: 549053.2
Subtracting 310 from 420 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
If we divide 1100 by 155, we get 7 and a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 549053.27
Deduct 1085 from 1100 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
155 can be fit into 150 0 times, resulting in a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 549053.27
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
If we divide 1500 by 155, we get 9 and a remainder of 105.
Use 9 as the next digit of our solution. 
Result so far: 549053.2709
Subtracting 1395 from 1500 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 13:
The number 155 fits into 1050 6 times, leaving a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 549053.27096
The remainder is 120 after subtracting 930 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 14:
If we divide 1200 by 155, we get 7 and a remainder of 115.
Use 7 as the next digit of our solution. 
Result so far: 549053.270967
If we take 1085 away from 1200, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 15:
If we divide 1150 by 155, we get 7 and a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 549053.2709677
The remainder is 65 after subtracting 1085 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 549053.2709677, with a leftover of 6.5e-07.
