We divide 63934639 by 620
Our goal is to divide 63934639 by 620.

Going ahead to step 1:
When dividing 6 by 620, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 620

Going ahead to step 2:
63 divided by 620 is 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 620

On to step 3:
The number 620 fits into 639 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 620 away from 639, we end up with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 620

Step 4:
If we divide 193 by 620, we get 0 and a remainder of 193.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 193 and we're left with 193.
Take the next digit (4) from the dividend and append it to 193, then repeat: 1934 / 620

Moving on to step 5:
620 goes into 1934 3 times with a remainder of 74.
The next digit of our result is 3. 
Result so far: 103.0
Subtracting 1860 from 1934 leaves us with 74.
Include the next digit (6) from the dividend after 74, then repeat: 746 / 620

Moving on to step 6:
620 can be fit into 746 1 times, resulting in a remainder of 126.
Put 1 as the next digit of the answer. 
Result so far: 1031.0
Subtract 620 from 746 to get 126.
Fetch the next digit (3) from the dividend, attach it to 126 and continue: 1263 / 620

Step 7:
If we divide 1263 by 620, we get 2 and a remainder of 23.
The next digit of our result is 2. 
Result so far: 10312.0
If we take 1240 away from 1263, we end up with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 620

Step 8:
620 can be fit into 239 0 times, resulting in a remainder of 239.
Put 0 as the next digit of the answer. 
Result so far: 103120.0
The remainder is 239 after subtracting 0 from 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 9:
If we divide 2390 by 620, we get 3 and a remainder of 530.
Put 3 as the next digit of the answer. 
Result so far: 103120.3
Deduct 1860 from 2390 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 10:
If we divide 5300 by 620, we get 8 and a remainder of 340.
Write down 8 as next digit of the result. 
Result so far: 103120.38
If we take 4960 away from 5300, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 11:
If we divide 3400 by 620, we get 5 and a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 103120.385
If we subtract 3100 from 3400, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 12:
620 can be fit into 3000 4 times, resulting in a remainder of 520.
Use 4 as the next digit of our solution. 
Result so far: 103120.3854
Subtracting 2480 from 3000 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 13:
If we divide 5200 by 620, we get 8 and a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 103120.38548
Subtracting 4960 from 5200 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 14:
620 can be fit into 2400 3 times, resulting in a remainder of 540.
Put 3 as the next digit of the answer. 
Result so far: 103120.385483
Subtracting 1860 from 2400 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 15:
620 can be fit into 5400 8 times, resulting in a remainder of 440.
The number 8 becomes the next digit in our result. 
Result so far: 103120.3854838
If we take 4960 away from 5400, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 16:
620 goes into 4400 7 times with a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 103120.38548387
Subtract 4340 from 4400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 103120.38548387 and a remainder of 6e-08.
