We look at the division of 40218991 by 446 
We're looking to find how many times 446 goes into 40218991.

Going ahead to step 1:
4 divided by 446 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 446

Step 2:
446 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 446

Let's proceed to step 3:
446 can be fit into 402 0 times, resulting in a remainder of 402.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 402 and we're left with 402.
Include the next digit (1) from the dividend after 402, then repeat: 4021 / 446

Going ahead to step 4:
4021 divided by 446 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 4014 from 4021 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 446

Moving on to step 5:
When dividing 78 by 446, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 90.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 446

On to step 6:
446 goes into 789 1 times with a remainder of 343.
The next digit of our result is 1. 
Result so far: 901.0
Deduct 446 from 789 and we're left with 343.
Include the next digit (9) from the dividend after 343, then repeat: 3439 / 446

Going ahead to step 7:
446 goes into 3439 7 times with a remainder of 317.
Use 7 as the next digit of our solution. 
Result so far: 9017.0
If we take 3122 away from 3439, we end up with 317.
Bring next digit (1) of the dividend behind the 317 and repeat the process: 3171 / 446

Advancing to step 8:
3171 divided by 446 is 7 with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 90177.0
Deduct 3122 from 3171 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
446 goes into 490 1 times with a remainder of 44.
The next digit of our result is 1. 
Result so far: 90177.1
If we subtract 446 from 490, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
446 can be fit into 440 0 times, resulting in a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 90177.1
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 11:
4400 divided by 446 is 9 with a remainder of 386.
The number 9 becomes the next digit in our result. 
Result so far: 90177.109
The remainder is 386 after subtracting 4014 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 12:
If we divide 3860 by 446, we get 8 and a remainder of 292.
Use 8 as the next digit of our solution. 
Result so far: 90177.1098
If we take 3568 away from 3860, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 13:
446 can be fit into 2920 6 times, resulting in a remainder of 244.
Write down 6 as next digit of the result. 
Result so far: 90177.10986
The remainder is 244 after subtracting 2676 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 14:
446 can be fit into 2440 5 times, resulting in a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 90177.109865
The remainder is 210 after subtracting 2230 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 15:
The number 446 fits into 2100 4 times, leaving a remainder of 316.
Put 4 as the next digit of the answer. 
Result so far: 90177.1098654
Subtracting 1784 from 2100 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 16:
The number 446 fits into 3160 7 times, leaving a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 90177.10986547
The remainder is 38 after subtracting 3122 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 90177.10986547 with a remaining 3.8e-08.
