35839687 ÷ 85 
We want to figure out the number of times 35839687 can be divided by 85.

On to step 1:
The number 85 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 85

Going ahead to step 2:
If we divide 35 by 85, we get 0 and a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 85

Moving on to step 3:
85 can be fit into 358 4 times, resulting in a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 340 away from 358, we end up with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 85

Advancing to step 4:
85 can be fit into 183 2 times, resulting in a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 170 from 183 leaves us with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 85

Step 5:
When dividing 139 by 85, we get 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 421.0
If we take 85 away from 139, we end up with 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 85

Step 6:
85 can be fit into 546 6 times, resulting in a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 4216.0
If we take 510 away from 546, we end up with 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 85

On to step 7:
When dividing 368 by 85, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 42164.0
Subtracting 340 from 368 leaves us with 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 85

Let's proceed to step 8:
If we divide 287 by 85, we get 3 and a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 421643.0
Subtract 255 from 287 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
When dividing 320 by 85, we get 3 with a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 421643.3
The remainder is 65 after subtracting 255 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 10:
When dividing 650 by 85, we get 7 with a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 421643.37
Deduct 595 from 650 and we're left 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.

Let's proceed to step 11:
If we divide 550 by 85, we get 6 and a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 421643.376
Subtracting 510 from 550 leaves us 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.

Moving on to step 12:
85 goes into 400 4 times with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 421643.3764
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.

Let's proceed to step 13:
85 can be fit into 600 7 times, resulting in a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 421643.37647
If we take 595 away from 600, we end up 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.

On to step 14:
If we divide 50 by 85, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 421643.37647
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.

Going ahead to step 15:
85 can be fit into 500 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 421643.3764705
Deduct 425 from 500 and we're left 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.

Going ahead to step 16:
When dividing 750 by 85, we get 8 with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 421643.37647058
If we subtract 680 from 750, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 421643.37647058, with a leftover of 7e-08.
