Let's divide 813866 by 37
We want to figure out the number of times 813866 can be divided by 37.

Moving on to step 1:
The number 37 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 37

Advancing to step 2:
When dividing 81 by 37, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 74 from 81 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 37

Advancing to step 3:
37 goes into 73 1 times with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 37 from 73, we get 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 37

Going ahead to step 4:
If we divide 368 by 37, we get 9 and a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
If we subtract 333 from 368, we get 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 37

Advancing to step 5:
When dividing 356 by 37, we get 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 2199.0
If we subtract 333 from 356, we get 23.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 37

On to step 6:
37 can be fit into 236 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 21996.0
Subtracting 222 from 236 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
The number 37 fits into 140 3 times, leaving a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 21996.3
If we take 111 away from 140, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
When dividing 290 by 37, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 21996.37
If we subtract 259 from 290, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
37 goes into 310 8 times with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 21996.378
Subtract 296 from 310 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
37 goes into 140 3 times with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 21996.3783
Subtract 111 from 140 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 11:
If we divide 290 by 37, we get 7 and a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 21996.37837
If we subtract 259 from 290, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 12:
The number 37 fits into 310 8 times, leaving a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 21996.378378
If we take 296 away from 310, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
When dividing 140 by 37, we get 3 with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 21996.3783783
Subtract 111 from 140 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 14:
290 divided by 37 is 7 with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 21996.37837837
Subtracting 259 from 290 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 21996.37837837 with a remaining 3.1e-08.
