We're dividing 871290 by 37 
We want to divide 871290 by 37.

On to step 1:
If we divide 8 by 37, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 37

On to step 2:
37 can be fit into 87 2 times, resulting in a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 74 away from 87, we end up with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 37

Step 3:
37 goes into 131 3 times with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 111 from 131 to get 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 37

Let's proceed to step 4:
37 goes into 202 5 times with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 235.0
Deduct 185 from 202 and we're left with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 37

On to step 5:
37 can be fit into 179 4 times, resulting in a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 2354.0
The remainder is 31 after subtracting 148 from 179.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 37

Advancing to step 6:
When dividing 310 by 37, we get 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 23548.0
Deduct 296 from 310 and we're left 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.

Going ahead to step 7:
The number 37 fits into 140 3 times, leaving a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 23548.3
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.

On to step 8:
37 can be fit into 290 7 times, resulting in a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 23548.37
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.

Going ahead to step 9:
If we divide 310 by 37, we get 8 and a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 23548.378
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.

Let's proceed to step 10:
140 divided by 37 is 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 23548.3783
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.

Step 11:
37 can be fit into 290 7 times, resulting in a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 23548.37837
Deduct 259 from 290 and we're left 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.

Moving on to step 12:
37 can be fit into 310 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 23548.378378
The remainder is 14 after subtracting 296 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
140 divided by 37 is 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 23548.3783783
If we subtract 111 from 140, we 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.
Use 7 as the next digit of our solution. 
Result so far: 23548.37837837
If we take 259 away from 290, we end up 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.

The final outcome is 23548.37837837, with a leftover of 3.1e-08.
