We're dividing 36990374 by 870 
We want to divide 36990374 by 870.

Moving on to step 1:
870 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 870

Let's proceed to step 2:
If we divide 36 by 870, we get 0 and a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 870

Let's proceed to step 3:
369 divided by 870 is 0 with a remainder of 369.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 369 leaves us with 369.
Fetch the next digit (9) from the dividend, attach it to 369 and continue: 3699 / 870

On to step 4:
When dividing 3699 by 870, we get 4 with a remainder of 219.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3480 from 3699, we get 219.
Include the next digit (0) from the dividend after 219, then repeat: 2190 / 870

Going ahead to step 5:
2190 divided by 870 is 2 with a remainder of 450.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 450 after subtracting 1740 from 2190.
Include the next digit (3) from the dividend after 450, then repeat: 4503 / 870

Advancing to step 6:
870 can be fit into 4503 5 times, resulting in a remainder of 153.
The next digit of our result is 5. 
Result so far: 425.0
Subtracting 4350 from 4503 leaves us with 153.
Take the next digit (7) from the dividend and append it to 153, then repeat: 1537 / 870

Advancing to step 7:
870 can be fit into 1537 1 times, resulting in a remainder of 667.
Use 1 as the next digit of our solution. 
Result so far: 4251.0
The remainder is 667 after subtracting 870 from 1537.
Fetch the next digit (4) from the dividend, attach it to 667 and continue: 6674 / 870

Step 8:
If we divide 6674 by 870, we get 7 and a remainder of 584.
Use 7 as the next digit of our solution. 
Result so far: 42517.0
The remainder is 584 after subtracting 6090 from 6674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 9:
5840 divided by 870 is 6 with a remainder of 620.
The next digit of our result is 6. 
Result so far: 42517.6
Subtracting 5220 from 5840 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 10:
870 can be fit into 6200 7 times, resulting in a remainder of 110.
Write down 7 as next digit of the result. 
Result so far: 42517.67
If we take 6090 away from 6200, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 11:
The number 870 fits into 1100 1 times, leaving a remainder of 230.
Record the quotient 1 as the next digit in the result. 
Result so far: 42517.671
Subtract 870 from 1100 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 12:
2300 divided by 870 is 2 with a remainder of 560.
Put 2 as the next digit of the answer. 
Result so far: 42517.6712
Subtracting 1740 from 2300 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 13:
5600 divided by 870 is 6 with a remainder of 380.
Put 6 as the next digit of the answer. 
Result so far: 42517.67126
Subtracting 5220 from 5600 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 14:
870 goes into 3800 4 times with a remainder of 320.
The next digit of our result is 4. 
Result so far: 42517.671264
Subtracting 3480 from 3800 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
870 goes into 3200 3 times with a remainder of 590.
The number 3 becomes the next digit in our result. 
Result so far: 42517.6712643
If we subtract 2610 from 3200, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 16:
If we divide 5900 by 870, we get 6 and a remainder of 680.
Use 6 as the next digit of our solution. 
Result so far: 42517.67126436
Subtract 5220 from 5900 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

The quotient of the division is 42517.67126436, and the remainder is 6.8e-07.
