85458799 divided by 155 
Our goal is to divide 85458799 by 155.

On to step 1:
If we divide 8 by 155, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 155

Moving on to step 2:
85 divided by 155 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Take the next digit (4) from the dividend and append it to 85, then repeat: 854 / 155

Moving on to step 3:
When dividing 854 by 155, we get 5 with a remainder of 79.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 775 away from 854, we end up with 79.
Append the next digit (5) from the dividend to 79 and continue with: 795 / 155

Let's proceed to step 4:
155 goes into 795 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 55.0
The remainder is 20 after subtracting 775 from 795.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 155

Advancing to step 5:
When dividing 208 by 155, we get 1 with a remainder of 53.
The next digit of our result is 1. 
Result so far: 551.0
Subtract 155 from 208 to get 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 155

Step 6:
155 can be fit into 537 3 times, resulting in a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 5513.0
Subtracting 465 from 537 leaves us with 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 155

Let's proceed to step 7:
If we divide 729 by 155, we get 4 and a remainder of 109.
Put 4 as the next digit of the answer. 
Result so far: 55134.0
If we take 620 away from 729, we end up with 109.
Bring next digit (9) of the dividend behind the 109 and repeat the process: 1099 / 155

Advancing to step 8:
The number 155 fits into 1099 7 times, leaving a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 551347.0
If we take 1085 away from 1099, we end up 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.

Let's proceed to step 9:
The number 155 fits into 140 0 times, leaving a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 551347.0
If we subtract 0 from 140, we 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.

Going ahead to step 10:
155 goes into 1400 9 times with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 551347.09
Deduct 1395 from 1400 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
155 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 551347.09
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
The number 155 fits into 500 3 times, leaving a remainder of 35.
The next digit of our result is 3. 
Result so far: 551347.0903
Deduct 465 from 500 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
If we divide 350 by 155, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 551347.09032
If we take 310 away from 350, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
When dividing 400 by 155, we get 2 with a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 551347.090322
If we subtract 310 from 400, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final result is 551347.090322 with a remainder of 9e-06.
