We're dividing 36871990 by 817 
We want to divide 36871990 by 817.

On to step 1:
3 divided by 817 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 817

Moving on to step 2:
If we divide 36 by 817, we get 0 and a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 817

Step 3:
368 divided by 817 is 0 with a remainder of 368.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 368 after subtracting 0 from 368.
Append the next digit (7) from the dividend to 368 and continue with: 3687 / 817

Advancing to step 4:
817 can be fit into 3687 4 times, resulting in a remainder of 419.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 3268 from 3687 leaves us with 419.
Include the next digit (1) from the dividend after 419, then repeat: 4191 / 817

On to step 5:
When dividing 4191 by 817, we get 5 with a remainder of 106.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we subtract 4085 from 4191, we get 106.
Append the next digit (9) from the dividend to 106 and continue with: 1069 / 817

Let's proceed to step 6:
817 goes into 1069 1 times with a remainder of 252.
The next digit of our result is 1. 
Result so far: 451.0
If we subtract 817 from 1069, we get 252.
Fetch the next digit (9) from the dividend, attach it to 252 and continue: 2529 / 817

Let's proceed to step 7:
817 goes into 2529 3 times with a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 4513.0
Deduct 2451 from 2529 and we're left with 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 817

Advancing to step 8:
If we divide 780 by 817, we get 0 and a remainder of 780.
The number 0 becomes the next digit in our result. 
Result so far: 45130.0
Deduct 0 from 780 and we're left with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Moving on to step 9:
The number 817 fits into 7800 9 times, leaving a remainder of 447.
Use 9 as the next digit of our solution. 
Result so far: 45130.9
Subtracting 7353 from 7800 leaves us with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

On to step 10:
The number 817 fits into 4470 5 times, leaving a remainder of 385.
Put 5 as the next digit of the answer. 
Result so far: 45130.95
If we take 4085 away from 4470, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 11:
3850 divided by 817 is 4 with a remainder of 582.
Record the quotient 4 as the next digit in the result. 
Result so far: 45130.954
If we subtract 3268 from 3850, we get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Moving on to step 12:
817 goes into 5820 7 times with a remainder of 101.
Record the quotient 7 as the next digit in the result. 
Result so far: 45130.9547
Deduct 5719 from 5820 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 13:
817 goes into 1010 1 times with a remainder of 193.
Write down 1 as next digit of the result. 
Result so far: 45130.95471
Subtract 817 from 1010 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 14:
817 goes into 1930 2 times with a remainder of 296.
The next digit of our result is 2. 
Result so far: 45130.954712
Deduct 1634 from 1930 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 15:
If we divide 2960 by 817, we get 3 and a remainder of 509.
The number 3 becomes the next digit in our result. 
Result so far: 45130.9547123
Deduct 2451 from 2960 and we're left with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

On to step 16:
5090 divided by 817 is 6 with a remainder of 188.
Record the quotient 6 as the next digit in the result. 
Result so far: 45130.95471236
The remainder is 188 after subtracting 4902 from 5090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Our division results in 45130.95471236 with a remaining 1.88e-07.
