We look at the division of 31991820 by 46 
We want to figure out the number of times 31991820 can be divided by 46.

Let's proceed to step 1:
46 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 46

Let's proceed to step 2:
If we divide 31 by 46, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 46

Moving on to step 3:
The number 46 fits into 319 6 times, leaving a remainder of 43.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 276 from 319, we get 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 46

On to step 4:
46 goes into 439 9 times with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we take 414 away from 439, we end up with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 46

Going ahead to step 5:
251 divided by 46 is 5 with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 695.0
The remainder is 21 after subtracting 230 from 251.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 46

Going ahead to step 6:
The number 46 fits into 218 4 times, leaving a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 6954.0
Deduct 184 from 218 and we're left with 34.
Include the next digit (2) from the dividend after 34, then repeat: 342 / 46

Advancing to step 7:
46 goes into 342 7 times with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 69547.0
Subtract 322 from 342 to get 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 46

Step 8:
When dividing 200 by 46, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 695474.0
If we take 184 away from 200, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
46 goes into 160 3 times with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 695474.3
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
The number 46 fits into 220 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 695474.34
Subtract 184 from 220 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
The number 46 fits into 360 7 times, leaving a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 695474.347
If we subtract 322 from 360, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
The number 46 fits into 380 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 695474.3478
If we subtract 368 from 380, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
46 goes into 120 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 695474.34782
Deduct 92 from 120 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
46 goes into 280 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 695474.347826
If we take 276 away from 280, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 15:
46 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 695474.347826
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
400 divided by 46 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 695474.34782608
Subtract 368 from 400 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 695474.34782608 and a remainder of 3.2e-08.
