We look at the division of 53401011 by 865 
Our goal is to divide 53401011 by 865.

Step 1:
865 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 865

Let's proceed to step 2:
865 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 865

Let's proceed to step 3:
When dividing 534 by 865, we get 0 with a remainder of 534.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 534 to get 534.
Append the next digit (0) from the dividend to 534 and continue with: 5340 / 865

Step 4:
5340 divided by 865 is 6 with a remainder of 150.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 5190 from 5340 leaves us with 150.
Bring next digit (1) of the dividend behind the 150 and repeat the process: 1501 / 865

Step 5:
If we divide 1501 by 865, we get 1 and a remainder of 636.
The next digit of our result is 1. 
Result so far: 61.0
The remainder is 636 after subtracting 865 from 1501.
Fetch the next digit (0) from the dividend, attach it to 636 and continue: 6360 / 865

On to step 6:
When dividing 6360 by 865, we get 7 with a remainder of 305.
Use 7 as the next digit of our solution. 
Result so far: 617.0
The remainder is 305 after subtracting 6055 from 6360.
Bring next digit (1) of the dividend behind the 305 and repeat the process: 3051 / 865

Step 7:
3051 divided by 865 is 3 with a remainder of 456.
Write down 3 as next digit of the result. 
Result so far: 6173.0
If we subtract 2595 from 3051, we get 456.
Fetch the next digit (1) from the dividend, attach it to 456 and continue: 4561 / 865

Let's proceed to step 8:
865 can be fit into 4561 5 times, resulting in a remainder of 236.
Record the quotient 5 as the next digit in the result. 
Result so far: 61735.0
If we subtract 4325 from 4561, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 9:
The number 865 fits into 2360 2 times, leaving a remainder of 630.
Put 2 as the next digit of the answer. 
Result so far: 61735.2
The remainder is 630 after subtracting 1730 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 10:
The number 865 fits into 6300 7 times, leaving a remainder of 245.
Put 7 as the next digit of the answer. 
Result so far: 61735.27
If we subtract 6055 from 6300, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 11:
865 can be fit into 2450 2 times, resulting in a remainder of 720.
Record the quotient 2 as the next digit in the result. 
Result so far: 61735.272
If we take 1730 away from 2450, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 12:
The number 865 fits into 7200 8 times, leaving a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 61735.2728
The remainder is 280 after subtracting 6920 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 13:
865 goes into 2800 3 times with a remainder of 205.
Write down 3 as next digit of the result. 
Result so far: 61735.27283
If we subtract 2595 from 2800, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 14:
When dividing 2050 by 865, we get 2 with a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 61735.272832
Deduct 1730 from 2050 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 15:
The number 865 fits into 3200 3 times, leaving a remainder of 605.
Put 3 as the next digit of the answer. 
Result so far: 61735.2728323
Deduct 2595 from 3200 and we're left with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Let's proceed to step 16:
865 can be fit into 6050 6 times, resulting in a remainder of 860.
The number 6 becomes the next digit in our result. 
Result so far: 61735.27283236
Subtracting 5190 from 6050 leaves us with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

The final result is 61735.27283236 with a remainder of 8.6e-07.
