We look at the division of 31665073 by 436 
We're looking to find how many times 436 goes into 31665073.

On to step 1:
The number 436 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 436

Let's proceed to step 2:
When dividing 31 by 436, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 436

Going ahead to step 3:
316 divided by 436 is 0 with a remainder of 316.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 316 after subtracting 0 from 316.
Include the next digit (6) from the dividend after 316, then repeat: 3166 / 436

Advancing to step 4:
If we divide 3166 by 436, we get 7 and a remainder of 114.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 3052 away from 3166, we end up with 114.
Append the next digit (5) from the dividend to 114 and continue with: 1145 / 436

Advancing to step 5:
436 can be fit into 1145 2 times, resulting in a remainder of 273.
The next digit of our result is 2. 
Result so far: 72.0
If we subtract 872 from 1145, we get 273.
Grab the next digit (0) from the dividend, add it to 273, then carry on: 2730 / 436

On to step 6:
When dividing 2730 by 436, we get 6 with a remainder of 114.
The next digit of our result is 6. 
Result so far: 726.0
The remainder is 114 after subtracting 2616 from 2730.
Fetch the next digit (7) from the dividend, attach it to 114 and continue: 1147 / 436

Let's proceed to step 7:
436 can be fit into 1147 2 times, resulting in a remainder of 275.
The number 2 becomes the next digit in our result. 
Result so far: 7262.0
Subtracting 872 from 1147 leaves us with 275.
Bring next digit (3) of the dividend behind the 275 and repeat the process: 2753 / 436

Going ahead to step 8:
436 can be fit into 2753 6 times, resulting in a remainder of 137.
The next digit of our result is 6. 
Result so far: 72626.0
Deduct 2616 from 2753 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 9:
The number 436 fits into 1370 3 times, leaving a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 72626.3
If we take 1308 away from 1370, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
When dividing 620 by 436, we get 1 with a remainder of 184.
The next digit of our result is 1. 
Result so far: 72626.31
If we subtract 436 from 620, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 11:
The number 436 fits into 1840 4 times, leaving a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 72626.314
Subtracting 1744 from 1840 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 12:
960 divided by 436 is 2 with a remainder of 88.
The next digit of our result is 2. 
Result so far: 72626.3142
Subtracting 872 from 960 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 13:
436 can be fit into 880 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 72626.31422
Subtracting 872 from 880 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 72626.31422 with a remaining 8e-06.
