84789864 divided by 402 
We're looking to find how many times 402 goes into 84789864.

Step 1:
402 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 402

On to step 2:
84 divided by 402 is 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Grab the next digit (7) from the dividend, add it to 84, then carry on: 847 / 402

Moving on to step 3:
402 goes into 847 2 times with a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 804 from 847, we get 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 402

On to step 4:
402 goes into 438 1 times with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 402 from 438 to get 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 402

Let's proceed to step 5:
If we divide 369 by 402, we get 0 and a remainder of 369.
The number 0 becomes the next digit in our result. 
Result so far: 210.0
If we take 0 away from 369, we end up with 369.
Grab the next digit (8) from the dividend, add it to 369, then carry on: 3698 / 402

Moving on to step 6:
When dividing 3698 by 402, we get 9 with a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 2109.0
Subtracting 3618 from 3698 leaves us with 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 402

Advancing to step 7:
806 divided by 402 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 21092.0
Subtract 804 from 806 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 402

Step 8:
If we divide 24 by 402, we get 0 and a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 210920.0
Subtracting 0 from 24 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
402 can be fit into 240 0 times, resulting in a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 210920.0
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 10:
The number 402 fits into 2400 5 times, leaving a remainder of 390.
The next digit of our result is 5. 
Result so far: 210920.05
Subtracting 2010 from 2400 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 11:
402 can be fit into 3900 9 times, resulting in a remainder of 282.
The number 9 becomes the next digit in our result. 
Result so far: 210920.059
Deduct 3618 from 3900 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 12:
The number 402 fits into 2820 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 210920.0597
Subtract 2814 from 2820 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
The number 402 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 210920.0597
Deduct 0 from 60 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.

Let's proceed to step 14:
402 can be fit into 600 1 times, resulting in a remainder of 198.
The next digit of our result is 1. 
Result so far: 210920.059701
If we subtract 402 from 600, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 15:
The number 402 fits into 1980 4 times, leaving a remainder of 372.
The number 4 becomes the next digit in our result. 
Result so far: 210920.0597014
Subtract 1608 from 1980 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 16:
3720 divided by 402 is 9 with a remainder of 102.
Put 9 as the next digit of the answer. 
Result so far: 210920.05970149
If we take 3618 away from 3720, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final outcome is 210920.05970149, with a leftover of 1.02e-07.
