Let's divide 121599 by 85
Let's see how many times 85 fits into 121599.

Moving on to step 1:
85 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 85

Step 2:
85 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 85

Step 3:
121 divided by 85 is 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 85 away from 121, we end up with 36.
Take the next digit (5) from the dividend and append it to 36, then repeat: 365 / 85

On to step 4:
85 can be fit into 365 4 times, resulting in a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 25 after subtracting 340 from 365.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 85

Advancing to step 5:
259 divided by 85 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Deduct 255 from 259 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 85

On to step 6:
When dividing 49 by 85, we get 0 with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 1430.0
Deduct 0 from 49 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
85 can be fit into 490 5 times, resulting in a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 1430.5
If we subtract 425 from 490, 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.

Advancing to step 8:
650 divided by 85 is 7 with a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 1430.57
If we take 595 away from 650, we end up 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.

Moving on to step 9:
When dividing 550 by 85, we get 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 1430.576
If we take 510 away from 550, 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.

On to step 10:
85 can be fit into 400 4 times, resulting in a remainder of 60.
The next digit of our result is 4. 
Result so far: 1430.5764
If we subtract 340 from 400, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
If we divide 600 by 85, we get 7 and a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 1430.57647
Subtract 595 from 600 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.

Going ahead to step 12:
If we divide 50 by 85, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1430.57647
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
85 can be fit into 500 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 1430.5764705
The remainder is 75 after subtracting 425 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 14:
If we divide 750 by 85, we get 8 and a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 1430.57647058
Deduct 680 from 750 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 1430.57647058 with a remaining 7e-08.
