We look at the division of 53452801 by 851 
We want to divide 53452801 by 851.

Step 1:
If we divide 5 by 851, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 851

Let's proceed to step 2:
The number 851 fits into 53 0 times, leaving 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.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 851

Moving on to step 3:
851 goes into 534 0 times with a remainder of 534.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 534 and we're left with 534.
Append the next digit (5) from the dividend to 534 and continue with: 5345 / 851

Moving on to step 4:
851 goes into 5345 6 times with a remainder of 239.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 5106 from 5345 to get 239.
Append the next digit (2) from the dividend to 239 and continue with: 2392 / 851

Let's proceed to step 5:
851 can be fit into 2392 2 times, resulting in a remainder of 690.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we subtract 1702 from 2392, we get 690.
Take the next digit (8) from the dividend and append it to 690, then repeat: 6908 / 851

Going ahead to step 6:
6908 divided by 851 is 8 with a remainder of 100.
The next digit of our result is 8. 
Result so far: 628.0
The remainder is 100 after subtracting 6808 from 6908.
Take the next digit (0) from the dividend and append it to 100, then repeat: 1000 / 851

On to step 7:
The number 851 fits into 1000 1 times, leaving a remainder of 149.
The next digit of our result is 1. 
Result so far: 6281.0
The remainder is 149 after subtracting 851 from 1000.
Include the next digit (1) from the dividend after 149, then repeat: 1491 / 851

Let's proceed to step 8:
851 goes into 1491 1 times with a remainder of 640.
Use 1 as the next digit of our solution. 
Result so far: 62811.0
Subtract 851 from 1491 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 9:
When dividing 6400 by 851, we get 7 with a remainder of 443.
Use 7 as the next digit of our solution. 
Result so far: 62811.7
Deduct 5957 from 6400 and we're left with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Moving on to step 10:
851 can be fit into 4430 5 times, resulting in a remainder of 175.
The next digit of our result is 5. 
Result so far: 62811.75
If we take 4255 away from 4430, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 11:
When dividing 1750 by 851, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 62811.752
Subtract 1702 from 1750 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
The number 851 fits into 480 0 times, leaving a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 62811.752
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 13:
If we divide 4800 by 851, we get 5 and a remainder of 545.
Record the quotient 5 as the next digit in the result. 
Result so far: 62811.75205
Deduct 4255 from 4800 and we're left with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Advancing to step 14:
When dividing 5450 by 851, we get 6 with a remainder of 344.
Use 6 as the next digit of our solution. 
Result so far: 62811.752056
Subtracting 5106 from 5450 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 15:
If we divide 3440 by 851, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 62811.7520564
Subtracting 3404 from 3440 leaves us with 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 16:
When dividing 360 by 851, we get 0 with a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 62811.7520564
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

After the division, we end up with 62811.7520564 and a remainder of 3.6e-07.
