We're dividing 81644990 by 374 
We're looking to find how many times 374 goes into 81644990.

Going ahead to step 1:
374 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 374

Moving on to step 2:
374 goes into 81 0 times with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (6) from the dividend and append it to 81, then repeat: 816 / 374

Step 3:
374 can be fit into 816 2 times, resulting in a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 748 away from 816, we end up with 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 374

Advancing to step 4:
374 can be fit into 684 1 times, resulting in a remainder of 310.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 310 after subtracting 374 from 684.
Include the next digit (4) from the dividend after 310, then repeat: 3104 / 374

Advancing to step 5:
The number 374 fits into 3104 8 times, leaving a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 218.0
If we take 2992 away from 3104, we end up with 112.
Append the next digit (9) from the dividend to 112 and continue with: 1129 / 374

Going ahead to step 6:
If we divide 1129 by 374, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 2183.0
If we take 1122 away from 1129, we end up with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 374

Advancing to step 7:
79 divided by 374 is 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 21830.0
If we take 0 away from 79, we end up with 79.
Grab the next digit (0) from the dividend, add it to 79, then carry on: 790 / 374

Let's proceed to step 8:
The number 374 fits into 790 2 times, leaving a remainder of 42.
The next digit of our result is 2. 
Result so far: 218302.0
The remainder is 42 after subtracting 748 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
The number 374 fits into 420 1 times, leaving a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 218302.1
If we take 374 away from 420, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
The number 374 fits into 460 1 times, leaving a remainder of 86.
The number 1 becomes the next digit in our result. 
Result so far: 218302.11
Deduct 374 from 460 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Our division results in 218302.11 with a remaining 0.086.
