We look at the division of 49789111 by 620 
We want to figure out the number of times 49789111 can be divided by 620.

Moving on to step 1:
620 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 620

Moving on to step 2:
If we divide 49 by 620, we get 0 and a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 620

Going ahead to step 3:
497 divided by 620 is 0 with a remainder of 497.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 497 after subtracting 0 from 497.
Append the next digit (8) from the dividend to 497 and continue with: 4978 / 620

Moving on to step 4:
620 goes into 4978 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 4960 from 4978 and we're left with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 620

Step 5:
620 goes into 189 0 times with a remainder of 189.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we take 0 away from 189, we end up with 189.
Fetch the next digit (1) from the dividend, attach it to 189 and continue: 1891 / 620

Step 6:
The number 620 fits into 1891 3 times, leaving a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 803.0
Deduct 1860 from 1891 and we're left with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 620

Moving on to step 7:
When dividing 311 by 620, we get 0 with a remainder of 311.
Write down 0 as next digit of the result. 
Result so far: 8030.0
Deduct 0 from 311 and we're left with 311.
Take the next digit (1) from the dividend and append it to 311, then repeat: 3111 / 620

Step 8:
620 goes into 3111 5 times with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 80305.0
The remainder is 11 after subtracting 3100 from 3111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
110 divided by 620 is 0 with a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 80305.0
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 10:
If we divide 1100 by 620, we get 1 and a remainder of 480.
Write down 1 as next digit of the result. 
Result so far: 80305.01
The remainder is 480 after subtracting 620 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 11:
4800 divided by 620 is 7 with a remainder of 460.
Write down 7 as next digit of the result. 
Result so far: 80305.017
Subtracting 4340 from 4800 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 12:
The number 620 fits into 4600 7 times, leaving a remainder of 260.
The next digit of our result is 7. 
Result so far: 80305.0177
Subtract 4340 from 4600 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Our division results in 80305.0177 with a remaining 0.0026.
