63812420 divided by 620 
We want to figure out the number of times 63812420 can be divided by 620.

Advancing to step 1:
620 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 620

Going ahead to step 2:
620 can be fit into 63 0 times, resulting in a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 620

Advancing to step 3:
620 can be fit into 638 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 620 away from 638, we end up with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 620

On to step 4:
When dividing 181 by 620, we get 0 with a remainder of 181.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 181 after subtracting 0 from 181.
Include the next digit (2) from the dividend after 181, then repeat: 1812 / 620

Going ahead to step 5:
620 goes into 1812 2 times with a remainder of 572.
Write down 2 as next digit of the result. 
Result so far: 102.0
The remainder is 572 after subtracting 1240 from 1812.
Take the next digit (4) from the dividend and append it to 572, then repeat: 5724 / 620

Advancing to step 6:
If we divide 5724 by 620, we get 9 and a remainder of 144.
The next digit of our result is 9. 
Result so far: 1029.0
Subtract 5580 from 5724 to get 144.
Append the next digit (2) from the dividend to 144 and continue with: 1442 / 620

On to step 7:
When dividing 1442 by 620, we get 2 with a remainder of 202.
Record the quotient 2 as the next digit in the result. 
Result so far: 10292.0
The remainder is 202 after subtracting 1240 from 1442.
Fetch the next digit (0) from the dividend, attach it to 202 and continue: 2020 / 620

Advancing to step 8:
620 can be fit into 2020 3 times, resulting in a remainder of 160.
Write down 3 as next digit of the result. 
Result so far: 102923.0
If we take 1860 away from 2020, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 9:
If we divide 1600 by 620, we get 2 and a remainder of 360.
The next digit of our result is 2. 
Result so far: 102923.2
If we take 1240 away from 1600, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 10:
The number 620 fits into 3600 5 times, leaving a remainder of 500.
The next digit of our result is 5. 
Result so far: 102923.25
If we subtract 3100 from 3600, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 11:
If we divide 5000 by 620, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 102923.258
Deduct 4960 from 5000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
The number 620 fits into 400 0 times, leaving a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 102923.258
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 13:
If we divide 4000 by 620, we get 6 and a remainder of 280.
Record the quotient 6 as the next digit in the result. 
Result so far: 102923.25806
Deduct 3720 from 4000 and we're left with 280.
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 14:
The number 620 fits into 2800 4 times, leaving a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 102923.258064
If we subtract 2480 from 2800, we get 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:
If we divide 3200 by 620, we get 5 and a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 102923.2580645
Subtracting 3100 from 3200 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 16:
When dividing 1000 by 620, we get 1 with a remainder of 380.
Put 1 as the next digit of the answer. 
Result so far: 102923.25806451
The remainder is 380 after subtracting 620 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Our division results in 102923.25806451 with a remaining 3.8e-07.
