79963542 divided by 620 
Let's see how many times 620 fits into 79963542.

On to step 1:
When dividing 7 by 620, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 620

Advancing to step 2:
620 goes into 79 0 times with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Bring next digit (9) of the dividend behind the 79 and repeat the process: 799 / 620

On to step 3:
620 goes into 799 1 times with a remainder of 179.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 620 from 799 and we're left with 179.
Grab the next digit (6) from the dividend, add it to 179, then carry on: 1796 / 620

Going ahead to step 4:
If we divide 1796 by 620, we get 2 and a remainder of 556.
The next digit of our result is 2. 
Result so far: 12.0
If we take 1240 away from 1796, we end up with 556.
Take the next digit (3) from the dividend and append it to 556, then repeat: 5563 / 620

Advancing to step 5:
The number 620 fits into 5563 8 times, leaving a remainder of 603.
Put 8 as the next digit of the answer. 
Result so far: 128.0
If we take 4960 away from 5563, we end up with 603.
Append the next digit (5) from the dividend to 603 and continue with: 6035 / 620

Step 6:
The number 620 fits into 6035 9 times, leaving a remainder of 455.
Write down 9 as next digit of the result. 
Result so far: 1289.0
Deduct 5580 from 6035 and we're left with 455.
Bring next digit (4) of the dividend behind the 455 and repeat the process: 4554 / 620

Step 7:
620 goes into 4554 7 times with a remainder of 214.
Write down 7 as next digit of the result. 
Result so far: 12897.0
The remainder is 214 after subtracting 4340 from 4554.
Take the next digit (2) from the dividend and append it to 214, then repeat: 2142 / 620

Going ahead to step 8:
2142 divided by 620 is 3 with a remainder of 282.
Put 3 as the next digit of the answer. 
Result so far: 128973.0
Deduct 1860 from 2142 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 9:
620 can be fit into 2820 4 times, resulting in a remainder of 340.
The next digit of our result is 4. 
Result so far: 128973.4
Subtract 2480 from 2820 to get 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 10:
If we divide 3400 by 620, we get 5 and a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 128973.45
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.

Going ahead to step 11:
620 can be fit into 3000 4 times, resulting in a remainder of 520.
Write down 4 as next digit of the result. 
Result so far: 128973.454
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.

Moving on to step 12:
5200 divided by 620 is 8 with a remainder of 240.
The next digit of our result is 8. 
Result so far: 128973.4548
Deduct 4960 from 5200 and we're left 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.

Step 13:
The number 620 fits into 2400 3 times, leaving a remainder of 540.
Use 3 as the next digit of our solution. 
Result so far: 128973.45483
Deduct 1860 from 2400 and we're left 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.

Going ahead to step 14:
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: 128973.454838
Deduct 4960 from 5400 and we're left 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.

On to 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: 128973.4548387
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.

Advancing to step 16:
600 divided by 620 is 0 with a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 128973.4548387
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.

The quotient of the division is 128973.4548387, and the remainder is 6e-07.
