We look at the division of 52512189 by 620 
We want to divide 52512189 by 620.

Step 1:
5 divided by 620 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 620

Step 2:
The number 620 fits into 52 0 times, leaving a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Include the next digit (5) from the dividend after 52, then repeat: 525 / 620

Advancing to step 3:
525 divided by 620 is 0 with a remainder of 525.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 525 and we're left with 525.
Fetch the next digit (1) from the dividend, attach it to 525 and continue: 5251 / 620

On to step 4:
5251 divided by 620 is 8 with a remainder of 291.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 291 after subtracting 4960 from 5251.
Grab the next digit (2) from the dividend, add it to 291, then carry on: 2912 / 620

Let's proceed to step 5:
If we divide 2912 by 620, we get 4 and a remainder of 432.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Deduct 2480 from 2912 and we're left with 432.
Take the next digit (1) from the dividend and append it to 432, then repeat: 4321 / 620

On to step 6:
620 can be fit into 4321 6 times, resulting in a remainder of 601.
Put 6 as the next digit of the answer. 
Result so far: 846.0
Deduct 3720 from 4321 and we're left with 601.
Bring next digit (8) of the dividend behind the 601 and repeat the process: 6018 / 620

Going ahead to step 7:
If we divide 6018 by 620, we get 9 and a remainder of 438.
Use 9 as the next digit of our solution. 
Result so far: 8469.0
Subtracting 5580 from 6018 leaves us with 438.
Grab the next digit (9) from the dividend, add it to 438, then carry on: 4389 / 620

Going ahead to step 8:
4389 divided by 620 is 7 with a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 84697.0
Deduct 4340 from 4389 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
620 goes into 490 0 times with a remainder of 490.
The next digit of our result is 0. 
Result so far: 84697.0
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 10:
The number 620 fits into 4900 7 times, leaving a remainder of 560.
Use 7 as the next digit of our solution. 
Result so far: 84697.07
Deduct 4340 from 4900 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 11:
The number 620 fits into 5600 9 times, leaving a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 84697.079
Subtracting 5580 from 5600 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
620 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 84697.079
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 13:
The number 620 fits into 2000 3 times, leaving a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 84697.07903
If we subtract 1860 from 2000, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 14:
When dividing 1400 by 620, we get 2 with a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 84697.079032
The remainder is 160 after subtracting 1240 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 15:
620 can be fit into 1600 2 times, resulting in a remainder of 360.
Record the quotient 2 as the next digit in the result. 
Result so far: 84697.0790322
Subtract 1240 from 1600 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.

The final result is 84697.0790322 with a remainder of 3.6e-06.
