45216809 divided by 831 
We're looking to find how many times 831 goes into 45216809.

On to step 1:
If we divide 4 by 831, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 831

Going ahead to step 2:
45 divided by 831 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 831

Going ahead to step 3:
If we divide 452 by 831, we get 0 and a remainder of 452.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 452 and we're left with 452.
Bring next digit (1) of the dividend behind the 452 and repeat the process: 4521 / 831

Step 4:
The number 831 fits into 4521 5 times, leaving a remainder of 366.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 4155 away from 4521, we end up with 366.
Grab the next digit (6) from the dividend, add it to 366, then carry on: 3666 / 831

Moving on to step 5:
831 goes into 3666 4 times with a remainder of 342.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we subtract 3324 from 3666, we get 342.
Append the next digit (8) from the dividend to 342 and continue with: 3428 / 831

Let's proceed to step 6:
831 can be fit into 3428 4 times, resulting in a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 544.0
If we subtract 3324 from 3428, we get 104.
Grab the next digit (0) from the dividend, add it to 104, then carry on: 1040 / 831

On to step 7:
The number 831 fits into 1040 1 times, leaving a remainder of 209.
Record the quotient 1 as the next digit in the result. 
Result so far: 5441.0
If we take 831 away from 1040, we end up with 209.
Fetch the next digit (9) from the dividend, attach it to 209 and continue: 2099 / 831

Let's proceed to step 8:
When dividing 2099 by 831, we get 2 with a remainder of 437.
Write down 2 as next digit of the result. 
Result so far: 54412.0
Deduct 1662 from 2099 and we're left with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Step 9:
When dividing 4370 by 831, we get 5 with a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 54412.5
If we take 4155 away from 4370, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 10:
831 goes into 2150 2 times with a remainder of 488.
Record the quotient 2 as the next digit in the result. 
Result so far: 54412.52
If we subtract 1662 from 2150, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 11:
When dividing 4880 by 831, we get 5 with a remainder of 725.
Use 5 as the next digit of our solution. 
Result so far: 54412.525
Subtract 4155 from 4880 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Going ahead to step 12:
831 goes into 7250 8 times with a remainder of 602.
Use 8 as the next digit of our solution. 
Result so far: 54412.5258
Deduct 6648 from 7250 and we're left with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Advancing to step 13:
831 goes into 6020 7 times with a remainder of 203.
The next digit of our result is 7. 
Result so far: 54412.52587
Deduct 5817 from 6020 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 14:
If we divide 2030 by 831, we get 2 and a remainder of 368.
Record the quotient 2 as the next digit in the result. 
Result so far: 54412.525872
The remainder is 368 after subtracting 1662 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 15:
The number 831 fits into 3680 4 times, leaving a remainder of 356.
Use 4 as the next digit of our solution. 
Result so far: 54412.5258724
Subtracting 3324 from 3680 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 16:
831 goes into 3560 4 times with a remainder of 236.
Use 4 as the next digit of our solution. 
Result so far: 54412.52587244
The remainder is 236 after subtracting 3324 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final outcome is 54412.52587244, with a leftover of 2.36e-07.
