12061545 divided by 858 
We're looking to find how many times 858 goes into 12061545.

Going ahead to step 1:
858 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 858

Step 2:
The number 858 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 858

Going ahead to step 3:
The number 858 fits into 120 0 times, leaving a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 120, we get 120.
Bring next digit (6) of the dividend behind the 120 and repeat the process: 1206 / 858

Going ahead to step 4:
858 goes into 1206 1 times with a remainder of 348.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 858 from 1206, we get 348.
Grab the next digit (1) from the dividend, add it to 348, then carry on: 3481 / 858

Moving on to step 5:
When dividing 3481 by 858, we get 4 with a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 3432 away from 3481, we end up with 49.
Fetch the next digit (5) from the dividend, attach it to 49 and continue: 495 / 858

On to step 6:
858 goes into 495 0 times with a remainder of 495.
The next digit of our result is 0. 
Result so far: 140.0
The remainder is 495 after subtracting 0 from 495.
Grab the next digit (4) from the dividend, add it to 495, then carry on: 4954 / 858

Step 7:
When dividing 4954 by 858, we get 5 with a remainder of 664.
Use 5 as the next digit of our solution. 
Result so far: 1405.0
Deduct 4290 from 4954 and we're left with 664.
Grab the next digit (5) from the dividend, add it to 664, then carry on: 6645 / 858

Moving on to step 8:
858 goes into 6645 7 times with a remainder of 639.
The next digit of our result is 7. 
Result so far: 14057.0
Deduct 6006 from 6645 and we're left with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Moving on to step 9:
858 can be fit into 6390 7 times, resulting in a remainder of 384.
Use 7 as the next digit of our solution. 
Result so far: 14057.7
Subtracting 6006 from 6390 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 10:
If we divide 3840 by 858, we get 4 and a remainder of 408.
Record the quotient 4 as the next digit in the result. 
Result so far: 14057.74
Subtracting 3432 from 3840 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 11:
858 goes into 4080 4 times with a remainder of 648.
Use 4 as the next digit of our solution. 
Result so far: 14057.744
If we take 3432 away from 4080, we end up with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Our division results in 14057.744 with a remaining 0.0648.
