We're dividing 84401986 by 820 
We're looking to find how many times 820 goes into 84401986.

Going ahead to step 1:
When dividing 8 by 820, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 820

Moving on to step 2:
820 can be fit into 84 0 times, resulting in a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Bring next digit (4) of the dividend behind the 84 and repeat the process: 844 / 820

Advancing to step 3:
820 can be fit into 844 1 times, resulting in a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 820 from 844 leaves us with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 820

On to step 4:
820 goes into 240 0 times with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 240 after subtracting 0 from 240.
Bring next digit (1) of the dividend behind the 240 and repeat the process: 2401 / 820

Let's proceed to step 5:
820 can be fit into 2401 2 times, resulting in a remainder of 761.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtracting 1640 from 2401 leaves us with 761.
Bring next digit (9) of the dividend behind the 761 and repeat the process: 7619 / 820

On to step 6:
When dividing 7619 by 820, we get 9 with a remainder of 239.
Put 9 as the next digit of the answer. 
Result so far: 1029.0
If we take 7380 away from 7619, we end up with 239.
Fetch the next digit (8) from the dividend, attach it to 239 and continue: 2398 / 820

Step 7:
2398 divided by 820 is 2 with a remainder of 758.
The next digit of our result is 2. 
Result so far: 10292.0
Subtract 1640 from 2398 to get 758.
Include the next digit (6) from the dividend after 758, then repeat: 7586 / 820

Advancing to step 8:
When dividing 7586 by 820, we get 9 with a remainder of 206.
The number 9 becomes the next digit in our result. 
Result so far: 102929.0
The remainder is 206 after subtracting 7380 from 7586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 9:
2060 divided by 820 is 2 with a remainder of 420.
Write down 2 as next digit of the result. 
Result so far: 102929.2
Deduct 1640 from 2060 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 10:
820 goes into 4200 5 times with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 102929.25
If we subtract 4100 from 4200, we 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.

Moving on to step 11:
When dividing 1000 by 820, we get 1 with a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 102929.251
Subtracting 820 from 1000 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 12:
When dividing 1800 by 820, we get 2 with a remainder of 160.
The next digit of our result is 2. 
Result so far: 102929.2512
Deduct 1640 from 1800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
The number 820 fits into 1600 1 times, leaving a remainder of 780.
The number 1 becomes the next digit in our result. 
Result so far: 102929.25121
The remainder is 780 after subtracting 820 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 14:
If we divide 7800 by 820, we get 9 and a remainder of 420.
Use 9 as the next digit of our solution. 
Result so far: 102929.251219
Subtracting 7380 from 7800 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 15:
If we divide 4200 by 820, we get 5 and a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 102929.2512195
Subtract 4100 from 4200 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.

Let's proceed to step 16:
If we divide 1000 by 820, we get 1 and a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 102929.25121951
Subtracting 820 from 1000 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final result is 102929.25121951 with a remainder of 1.8e-07.
