We're dividing 21308562 by 620 
Our goal is to divide 21308562 by 620.

Moving on to step 1:
2 divided by 620 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 620

Let's proceed to step 2:
21 divided by 620 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 620

Step 3:
620 goes into 213 0 times with a remainder of 213.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 213 to get 213.
Take the next digit (0) from the dividend and append it to 213, then repeat: 2130 / 620

Step 4:
620 goes into 2130 3 times with a remainder of 270.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 270 after subtracting 1860 from 2130.
Fetch the next digit (8) from the dividend, attach it to 270 and continue: 2708 / 620

Advancing to step 5:
The number 620 fits into 2708 4 times, leaving a remainder of 228.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we take 2480 away from 2708, we end up with 228.
Grab the next digit (5) from the dividend, add it to 228, then carry on: 2285 / 620

Advancing to step 6:
620 can be fit into 2285 3 times, resulting in a remainder of 425.
Put 3 as the next digit of the answer. 
Result so far: 343.0
The remainder is 425 after subtracting 1860 from 2285.
Grab the next digit (6) from the dividend, add it to 425, then carry on: 4256 / 620

On to step 7:
If we divide 4256 by 620, we get 6 and a remainder of 536.
The next digit of our result is 6. 
Result so far: 3436.0
If we take 3720 away from 4256, we end up with 536.
Append the next digit (2) from the dividend to 536 and continue with: 5362 / 620

Going ahead to step 8:
The number 620 fits into 5362 8 times, leaving a remainder of 402.
Record the quotient 8 as the next digit in the result. 
Result so far: 34368.0
Subtracting 4960 from 5362 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 9:
When dividing 4020 by 620, we get 6 with a remainder of 300.
Use 6 as the next digit of our solution. 
Result so far: 34368.6
The remainder is 300 after subtracting 3720 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
3000 divided by 620 is 4 with a remainder of 520.
Record the quotient 4 as the next digit in the result. 
Result so far: 34368.64
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.

Moving on to step 11:
620 can be fit into 5200 8 times, resulting in a remainder of 240.
The next digit of our result is 8. 
Result so far: 34368.648
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.

Advancing to step 12:
If we divide 2400 by 620, we get 3 and a remainder of 540.
The next digit of our result is 3. 
Result so far: 34368.6483
Subtract 1860 from 2400 to get 540.
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 13:
When dividing 5400 by 620, we get 8 with a remainder of 440.
Use 8 as the next digit of our solution. 
Result so far: 34368.64838
The remainder is 440 after subtracting 4960 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 14:
620 goes into 4400 7 times with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 34368.648387
Deduct 4340 from 4400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 15:
If we divide 600 by 620, we get 0 and a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 34368.648387
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 16:
When dividing 6000 by 620, we get 9 with a remainder of 420.
Put 9 as the next digit of the answer. 
Result so far: 34368.64838709
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.

The final outcome is 34368.64838709, with a leftover of 4.2e-07.
