49145791 divided by 620 
We want to figure out the number of times 49145791 can be divided by 620.

On to step 1:
If we divide 4 by 620, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 620

Moving on to step 2:
When dividing 49 by 620, we get 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 620

On to step 3:
If we divide 491 by 620, we get 0 and a remainder of 491.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 491, we end up with 491.
Grab the next digit (4) from the dividend, add it to 491, then carry on: 4914 / 620

On to step 4:
620 goes into 4914 7 times with a remainder of 574.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4340 from 4914, we get 574.
Include the next digit (5) from the dividend after 574, then repeat: 5745 / 620

Moving on to step 5:
620 can be fit into 5745 9 times, resulting in a remainder of 165.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtracting 5580 from 5745 leaves us with 165.
Grab the next digit (7) from the dividend, add it to 165, then carry on: 1657 / 620

Step 6:
The number 620 fits into 1657 2 times, leaving a remainder of 417.
The next digit of our result is 2. 
Result so far: 792.0
Subtract 1240 from 1657 to get 417.
Bring next digit (9) of the dividend behind the 417 and repeat the process: 4179 / 620

Advancing to step 7:
4179 divided by 620 is 6 with a remainder of 459.
The next digit of our result is 6. 
Result so far: 7926.0
Subtract 3720 from 4179 to get 459.
Take the next digit (1) from the dividend and append it to 459, then repeat: 4591 / 620

Step 8:
When dividing 4591 by 620, we get 7 with a remainder of 251.
Put 7 as the next digit of the answer. 
Result so far: 79267.0
The remainder is 251 after subtracting 4340 from 4591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 9:
The number 620 fits into 2510 4 times, leaving a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 79267.4
Subtract 2480 from 2510 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 620 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 79267.4
Subtract 0 from 300 to 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.

Going ahead to step 11:
When dividing 3000 by 620, we get 4 with a remainder of 520.
Write down 4 as next digit of the result. 
Result so far: 79267.404
If we take 2480 away from 3000, we end up 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.

Going ahead to step 12:
The number 620 fits into 5200 8 times, leaving a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 79267.4048
If we take 4960 away from 5200, we end up 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 13:
If we divide 2400 by 620, we get 3 and a remainder of 540.
The number 3 becomes the next digit in our result. 
Result so far: 79267.40483
The remainder is 540 after subtracting 1860 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 14:
If we divide 5400 by 620, we get 8 and a remainder of 440.
Record the quotient 8 as the next digit in the result. 
Result so far: 79267.404838
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 15:
When dividing 4400 by 620, we get 7 with a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 79267.4048387
If we subtract 4340 from 4400, we 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.

On to step 16:
When dividing 600 by 620, we get 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 79267.4048387
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

After the division, we end up with 79267.4048387 and a remainder of 6e-07.
