We're dividing 858405 by 37 
We want to figure out the number of times 858405 can be divided by 37.

On to step 1:
8 divided by 37 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 37

Advancing to step 2:
37 goes into 85 2 times with a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 74 from 85, we get 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 37

On to step 3:
If we divide 118 by 37, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 23.0
If we take 111 away from 118, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 37

Going ahead to step 4:
The number 37 fits into 74 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 232.0
If we subtract 74 from 74, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 37

Let's proceed to step 5:
37 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2320.0
If we subtract 0 from 0, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 37

Advancing to step 6:
When dividing 5 by 37, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 23200.0
Subtract 0 from 5 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.

Let's proceed to step 7:
37 can be fit into 50 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 23200.1
The remainder is 13 after subtracting 37 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
When dividing 130 by 37, we get 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 23200.13
Subtracting 111 from 130 leaves us 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.

Advancing to step 9:
190 divided by 37 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 23200.135
If we subtract 185 from 190, we 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.

Let's proceed to step 10:
37 goes into 50 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 23200.1351
Deduct 37 from 50 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
37 goes into 130 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 23200.13513
If we subtract 111 from 130, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 12:
190 divided by 37 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 23200.135135
If we take 185 away from 190, 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.

Going ahead to step 13:
When dividing 50 by 37, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 23200.1351351
Subtract 37 from 50 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 14:
37 goes into 130 3 times with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 23200.13513513
Subtract 111 from 130 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 23200.13513513 and a remainder of 1.9e-08.
