83321778 ÷ 620 
We want to figure out the number of times 83321778 can be divided by 620.

Let's proceed to step 1:
If we divide 8 by 620, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 620

Advancing to step 2:
620 goes into 83 0 times with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Take the next digit (3) from the dividend and append it to 83, then repeat: 833 / 620

Going ahead to step 3:
620 can be fit into 833 1 times, resulting in a remainder of 213.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 213 after subtracting 620 from 833.
Fetch the next digit (2) from the dividend, attach it to 213 and continue: 2132 / 620

On to step 4:
The number 620 fits into 2132 3 times, leaving a remainder of 272.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 272 after subtracting 1860 from 2132.
Fetch the next digit (1) from the dividend, attach it to 272 and continue: 2721 / 620

On to step 5:
620 can be fit into 2721 4 times, resulting in a remainder of 241.
Put 4 as the next digit of the answer. 
Result so far: 134.0
If we take 2480 away from 2721, we end up with 241.
Fetch the next digit (7) from the dividend, attach it to 241 and continue: 2417 / 620

Step 6:
When dividing 2417 by 620, we get 3 with a remainder of 557.
Write down 3 as next digit of the result. 
Result so far: 1343.0
If we subtract 1860 from 2417, we get 557.
Take the next digit (7) from the dividend and append it to 557, then repeat: 5577 / 620

Step 7:
5577 divided by 620 is 8 with a remainder of 617.
Put 8 as the next digit of the answer. 
Result so far: 13438.0
If we take 4960 away from 5577, we end up with 617.
Take the next digit (8) from the dividend and append it to 617, then repeat: 6178 / 620

Advancing to step 8:
If we divide 6178 by 620, we get 9 and a remainder of 598.
The next digit of our result is 9. 
Result so far: 134389.0
If we take 5580 away from 6178, we end up with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Step 9:
The number 620 fits into 5980 9 times, leaving a remainder of 400.
The number 9 becomes the next digit in our result. 
Result so far: 134389.9
Subtracting 5580 from 5980 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 10:
The number 620 fits into 4000 6 times, leaving a remainder of 280.
The next digit of our result is 6. 
Result so far: 134389.96
If we subtract 3720 from 4000, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 11:
620 can be fit into 2800 4 times, resulting in a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 134389.964
If we take 2480 away from 2800, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
The number 620 fits into 3200 5 times, leaving a remainder of 100.
The next digit of our result is 5. 
Result so far: 134389.9645
Subtract 3100 from 3200 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
620 can be fit into 1000 1 times, resulting in a remainder of 380.
Record the quotient 1 as the next digit in the result. 
Result so far: 134389.96451
If we take 620 away from 1000, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 14:
620 goes into 3800 6 times with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 134389.964516
Subtract 3720 from 3800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 15:
If we divide 800 by 620, we get 1 and a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 134389.9645161
If we subtract 620 from 800, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 16:
1800 divided by 620 is 2 with a remainder of 560.
The next digit of our result is 2. 
Result so far: 134389.96451612
Subtract 1240 from 1800 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The quotient of the division is 134389.96451612, and the remainder is 5.6e-07.
