Let's divide 143551 by 85
We want to figure out the number of times 143551 can be divided by 85.

Step 1:
1 divided by 85 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 85

Going ahead to step 2:
85 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 85

Going ahead to step 3:
143 divided by 85 is 1 with a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 58 after subtracting 85 from 143.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 85

On to step 4:
85 can be fit into 585 6 times, resulting in a remainder of 75.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 510 from 585, we get 75.
Fetch the next digit (5) from the dividend, attach it to 75 and continue: 755 / 85

Moving on to step 5:
If we divide 755 by 85, we get 8 and a remainder of 75.
Write down 8 as next digit of the result. 
Result so far: 168.0
If we subtract 680 from 755, we get 75.
Take the next digit (1) from the dividend and append it to 75, then repeat: 751 / 85

Advancing to step 6:
751 divided by 85 is 8 with a remainder of 71.
Use 8 as the next digit of our solution. 
Result so far: 1688.0
The remainder is 71 after subtracting 680 from 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 7:
If we divide 710 by 85, we get 8 and a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 1688.8
Subtract 680 from 710 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 85, we get 3 and a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 1688.83
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
85 goes into 450 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 1688.835
Subtracting 425 from 450 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
85 goes into 250 2 times with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 1688.8352
If we subtract 170 from 250, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
85 can be fit into 800 9 times, resulting in a remainder of 35.
The next digit of our result is 9. 
Result so far: 1688.83529
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
85 goes into 350 4 times with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 1688.835294
Deduct 340 from 350 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1688.8352941
Subtracting 85 from 100 leaves us 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.

Let's proceed to step 14:
When dividing 150 by 85, we get 1 with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 1688.83529411
If we subtract 85 from 150, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 1688.83529411 with a remaining 6.5e-08.
