53343161 ÷ 109 
Let's see how many times 109 fits into 53343161.

Advancing to step 1:
If we divide 5 by 109, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 109

Let's proceed to step 2:
109 goes into 53 0 times with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Include the next digit (3) from the dividend after 53, then repeat: 533 / 109

Step 3:
If we divide 533 by 109, we get 4 and a remainder of 97.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 436 from 533 leaves us with 97.
Fetch the next digit (4) from the dividend, attach it to 97 and continue: 974 / 109

On to step 4:
109 goes into 974 8 times with a remainder of 102.
Use 8 as the next digit of our solution. 
Result so far: 48.0
The remainder is 102 after subtracting 872 from 974.
Fetch the next digit (3) from the dividend, attach it to 102 and continue: 1023 / 109

Advancing to step 5:
If we divide 1023 by 109, we get 9 and a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 489.0
Deduct 981 from 1023 and we're left with 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 109

Advancing to step 6:
421 divided by 109 is 3 with a remainder of 94.
Write down 3 as next digit of the result. 
Result so far: 4893.0
Subtract 327 from 421 to get 94.
Append the next digit (6) from the dividend to 94 and continue with: 946 / 109

Advancing to step 7:
946 divided by 109 is 8 with a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 48938.0
Subtract 872 from 946 to get 74.
Include the next digit (1) from the dividend after 74, then repeat: 741 / 109

Going ahead to step 8:
The number 109 fits into 741 6 times, leaving a remainder of 87.
The next digit of our result is 6. 
Result so far: 489386.0
Deduct 654 from 741 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 9:
870 divided by 109 is 7 with a remainder of 107.
Record the quotient 7 as the next digit in the result. 
Result so far: 489386.7
The remainder is 107 after subtracting 763 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 10:
109 goes into 1070 9 times with a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 489386.79
Subtracting 981 from 1070 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 11:
890 divided by 109 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 489386.798
If we take 872 away from 890, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
180 divided by 109 is 1 with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 489386.7981
Subtracting 109 from 180 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 13:
When dividing 710 by 109, we get 6 with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 489386.79816
If we subtract 654 from 710, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
When dividing 560 by 109, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 489386.798165
Subtracting 545 from 560 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 15:
If we divide 150 by 109, we get 1 and a remainder of 41.
The next digit of our result is 1. 
Result so far: 489386.7981651
The remainder is 41 after subtracting 109 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 16:
410 divided by 109 is 3 with a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 489386.79816513
Deduct 327 from 410 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The final result is 489386.79816513 with a remainder of 8.3e-08.
