We look at the division of 858594 by 61 
We're looking to find how many times 61 goes into 858594.

On to step 1:
When dividing 8 by 61, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 61

Let's proceed to step 2:
If we divide 85 by 61, we get 1 and a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
If we take 61 away from 85, we end up with 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 61

Step 3:
The number 61 fits into 248 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 14.0
If we take 244 away from 248, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 61

Going ahead to step 4:
61 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 140.0
Deduct 0 from 45 and we're left with 45.
Bring next digit (9) of the dividend behind the 45 and repeat the process: 459 / 61

Advancing to step 5:
The number 61 fits into 459 7 times, leaving a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 1407.0
If we take 427 away from 459, we end up with 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 61

Step 6:
61 can be fit into 324 5 times, resulting in a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 14075.0
Deduct 305 from 324 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
61 can be fit into 190 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 14075.3
If we subtract 183 from 190, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
When dividing 70 by 61, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 14075.31
Subtracting 61 from 70 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
The number 61 fits into 90 1 times, leaving a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 14075.311
The remainder is 29 after subtracting 61 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

After the division, we end up with 14075.311 and a remainder of 0.0029.
