53740969 ÷ 868 
We want to figure out the number of times 53740969 can be divided by 868.

Advancing to step 1:
5 divided by 868 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 868

Going ahead to step 2:
53 divided by 868 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 868

Moving on to step 3:
If we divide 537 by 868, we get 0 and a remainder of 537.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 537, we get 537.
Include the next digit (4) from the dividend after 537, then repeat: 5374 / 868

On to step 4:
When dividing 5374 by 868, we get 6 with a remainder of 166.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 5208 from 5374 to get 166.
Append the next digit (0) from the dividend to 166 and continue with: 1660 / 868

Let's proceed to step 5:
868 goes into 1660 1 times with a remainder of 792.
The next digit of our result is 1. 
Result so far: 61.0
Subtracting 868 from 1660 leaves us with 792.
Take the next digit (9) from the dividend and append it to 792, then repeat: 7929 / 868

Moving on to step 6:
The number 868 fits into 7929 9 times, leaving a remainder of 117.
The number 9 becomes the next digit in our result. 
Result so far: 619.0
The remainder is 117 after subtracting 7812 from 7929.
Bring next digit (6) of the dividend behind the 117 and repeat the process: 1176 / 868

Going ahead to step 7:
When dividing 1176 by 868, we get 1 with a remainder of 308.
The number 1 becomes the next digit in our result. 
Result so far: 6191.0
If we take 868 away from 1176, we end up with 308.
Append the next digit (9) from the dividend to 308 and continue with: 3089 / 868

Going ahead to step 8:
868 goes into 3089 3 times with a remainder of 485.
The number 3 becomes the next digit in our result. 
Result so far: 61913.0
Deduct 2604 from 3089 and we're left with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Advancing to step 9:
4850 divided by 868 is 5 with a remainder of 510.
The next digit of our result is 5. 
Result so far: 61913.5
Subtracting 4340 from 4850 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 10:
The number 868 fits into 5100 5 times, leaving a remainder of 760.
The number 5 becomes the next digit in our result. 
Result so far: 61913.55
Subtract 4340 from 5100 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

The final outcome is 61913.55, with a leftover of 0.76.
