84146151 ÷ 820 
We want to figure out the number of times 84146151 can be divided by 820.

Step 1:
820 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 820

Step 2:
The number 820 fits into 84 0 times, leaving a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Grab the next digit (1) from the dividend, add it to 84, then carry on: 841 / 820

Going ahead to step 3:
820 goes into 841 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 820 from 841 leaves us with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 820

Advancing to step 4:
When dividing 214 by 820, we get 0 with a remainder of 214.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 214 and we're left with 214.
Fetch the next digit (6) from the dividend, attach it to 214 and continue: 2146 / 820

Step 5:
820 can be fit into 2146 2 times, resulting in a remainder of 506.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
If we take 1640 away from 2146, we end up with 506.
Grab the next digit (1) from the dividend, add it to 506, then carry on: 5061 / 820

Advancing to step 6:
The number 820 fits into 5061 6 times, leaving a remainder of 141.
Write down 6 as next digit of the result. 
Result so far: 1026.0
Deduct 4920 from 5061 and we're left with 141.
Take the next digit (5) from the dividend and append it to 141, then repeat: 1415 / 820

Advancing to step 7:
820 goes into 1415 1 times with a remainder of 595.
Put 1 as the next digit of the answer. 
Result so far: 10261.0
The remainder is 595 after subtracting 820 from 1415.
Take the next digit (1) from the dividend and append it to 595, then repeat: 5951 / 820

Step 8:
If we divide 5951 by 820, we get 7 and a remainder of 211.
Use 7 as the next digit of our solution. 
Result so far: 102617.0
Subtract 5740 from 5951 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 9:
820 goes into 2110 2 times with a remainder of 470.
Write down 2 as next digit of the result. 
Result so far: 102617.2
Subtracting 1640 from 2110 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 10:
4700 divided by 820 is 5 with a remainder of 600.
Use 5 as the next digit of our solution. 
Result so far: 102617.25
The remainder is 600 after subtracting 4100 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 11:
820 goes into 6000 7 times with a remainder of 260.
Write down 7 as next digit of the result. 
Result so far: 102617.257
The remainder is 260 after subtracting 5740 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 12:
The number 820 fits into 2600 3 times, leaving a remainder of 140.
The number 3 becomes the next digit in our result. 
Result so far: 102617.2573
If we take 2460 away from 2600, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 13:
820 can be fit into 1400 1 times, resulting in a remainder of 580.
Record the quotient 1 as the next digit in the result. 
Result so far: 102617.25731
If we take 820 away from 1400, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 14:
820 goes into 5800 7 times with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 102617.257317
If we take 5740 away from 5800, we end up 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.

Let's proceed to step 15:
820 can be fit into 600 0 times, resulting in a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 102617.257317
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.

Moving on to step 16:
When dividing 6000 by 820, we get 7 with a remainder of 260.
The number 7 becomes the next digit in our result. 
Result so far: 102617.25731707
Deduct 5740 from 6000 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The quotient of the division is 102617.25731707, and the remainder is 2.6e-07.
