We look at the division of 48974568 by 620 
We're looking to find how many times 620 goes into 48974568.

Going ahead to step 1:
620 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 620

Moving on to step 2:
620 can be fit into 48 0 times, resulting in a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 620

On to step 3:
620 goes into 489 0 times with a remainder of 489.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 489 to get 489.
Grab the next digit (7) from the dividend, add it to 489, then carry on: 4897 / 620

Step 4:
620 can be fit into 4897 7 times, resulting in a remainder of 557.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 4340 from 4897 leaves us with 557.
Take the next digit (4) from the dividend and append it to 557, then repeat: 5574 / 620

Step 5:
When dividing 5574 by 620, we get 8 with a remainder of 614.
Put 8 as the next digit of the answer. 
Result so far: 78.0
The remainder is 614 after subtracting 4960 from 5574.
Take the next digit (5) from the dividend and append it to 614, then repeat: 6145 / 620

Going ahead to step 6:
If we divide 6145 by 620, we get 9 and a remainder of 565.
Use 9 as the next digit of our solution. 
Result so far: 789.0
If we take 5580 away from 6145, we end up with 565.
Fetch the next digit (6) from the dividend, attach it to 565 and continue: 5656 / 620

On to step 7:
When dividing 5656 by 620, we get 9 with a remainder of 76.
Write down 9 as next digit of the result. 
Result so far: 7899.0
Subtract 5580 from 5656 to get 76.
Append the next digit (8) from the dividend to 76 and continue with: 768 / 620

Going ahead to step 8:
620 can be fit into 768 1 times, resulting in a remainder of 148.
Write down 1 as next digit of the result. 
Result so far: 78991.0
If we take 620 away from 768, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 9:
If we divide 1480 by 620, we get 2 and a remainder of 240.
The next digit of our result is 2. 
Result so far: 78991.2
Subtracting 1240 from 1480 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 10:
620 can be fit into 2400 3 times, resulting in a remainder of 540.
Write down 3 as next digit of the result. 
Result so far: 78991.23
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.

On to step 11:
The number 620 fits into 5400 8 times, leaving a remainder of 440.
Put 8 as the next digit of the answer. 
Result so far: 78991.238
Subtract 4960 from 5400 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 12:
When dividing 4400 by 620, we get 7 with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 78991.2387
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.

Step 13:
600 divided by 620 is 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 78991.2387
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 14:
The number 620 fits into 6000 9 times, leaving a remainder of 420.
Write down 9 as next digit of the result. 
Result so far: 78991.238709
If we subtract 5580 from 6000, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 15:
620 can be fit into 4200 6 times, resulting in a remainder of 480.
The next digit of our result is 6. 
Result so far: 78991.2387096
If we take 3720 away from 4200, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 16:
4800 divided by 620 is 7 with a remainder of 460.
Put 7 as the next digit of the answer. 
Result so far: 78991.23870967
If we subtract 4340 from 4800, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

In conclusion, the division gives 78991.23870967 with a balance of 4.6e-07.
