We look at the division of 31192729 by 438 
We want to figure out the number of times 31192729 can be divided by 438.

On to step 1:
3 divided by 438 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 438

Moving on to step 2:
The number 438 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 438

Advancing to step 3:
When dividing 311 by 438, we get 0 with a remainder of 311.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 311 after subtracting 0 from 311.
Grab the next digit (9) from the dividend, add it to 311, then carry on: 3119 / 438

Advancing to step 4:
The number 438 fits into 3119 7 times, leaving a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 53 after subtracting 3066 from 3119.
Fetch the next digit (2) from the dividend, attach it to 53 and continue: 532 / 438

Moving on to step 5:
If we divide 532 by 438, we get 1 and a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we subtract 438 from 532, we get 94.
Include the next digit (7) from the dividend after 94, then repeat: 947 / 438

Advancing to step 6:
The number 438 fits into 947 2 times, leaving a remainder of 71.
The next digit of our result is 2. 
Result so far: 712.0
Deduct 876 from 947 and we're left with 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 438

Advancing to step 7:
The number 438 fits into 712 1 times, leaving a remainder of 274.
Write down 1 as next digit of the result. 
Result so far: 7121.0
Subtracting 438 from 712 leaves us with 274.
Fetch the next digit (9) from the dividend, attach it to 274 and continue: 2749 / 438

Going ahead to step 8:
If we divide 2749 by 438, we get 6 and a remainder of 121.
The next digit of our result is 6. 
Result so far: 71216.0
Subtracting 2628 from 2749 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 9:
438 can be fit into 1210 2 times, resulting in a remainder of 334.
Record the quotient 2 as the next digit in the result. 
Result so far: 71216.2
If we subtract 876 from 1210, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 10:
If we divide 3340 by 438, we get 7 and a remainder of 274.
Write down 7 as next digit of the result. 
Result so far: 71216.27
If we take 3066 away from 3340, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 11:
If we divide 2740 by 438, we get 6 and a remainder of 112.
The next digit of our result is 6. 
Result so far: 71216.276
Subtract 2628 from 2740 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 12:
If we divide 1120 by 438, we get 2 and a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 71216.2762
Subtract 876 from 1120 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 13:
When dividing 2440 by 438, we get 5 with a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 71216.27625
Subtract 2190 from 2440 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 14:
The number 438 fits into 2500 5 times, leaving a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 71216.276255
Subtract 2190 from 2500 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

After the division, we end up with 71216.276255 and a remainder of 3.1e-05.
