84502739 ÷ 397 
We want to figure out the number of times 84502739 can be divided by 397.

On to step 1:
397 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 397

On to step 2:
84 divided by 397 is 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Take the next digit (5) from the dividend and append it to 84, then repeat: 845 / 397

Let's proceed to step 3:
The number 397 fits into 845 2 times, leaving a remainder of 51.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 794 from 845, we get 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 397

Going ahead to step 4:
The number 397 fits into 510 1 times, leaving a remainder of 113.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 397 from 510 leaves us with 113.
Fetch the next digit (2) from the dividend, attach it to 113 and continue: 1132 / 397

Advancing to step 5:
The number 397 fits into 1132 2 times, leaving a remainder of 338.
The number 2 becomes the next digit in our result. 
Result so far: 212.0
Deduct 794 from 1132 and we're left with 338.
Bring next digit (7) of the dividend behind the 338 and repeat the process: 3387 / 397

On to step 6:
397 can be fit into 3387 8 times, resulting in a remainder of 211.
Use 8 as the next digit of our solution. 
Result so far: 2128.0
Subtract 3176 from 3387 to get 211.
Bring next digit (3) of the dividend behind the 211 and repeat the process: 2113 / 397

Step 7:
If we divide 2113 by 397, we get 5 and a remainder of 128.
Use 5 as the next digit of our solution. 
Result so far: 21285.0
If we subtract 1985 from 2113, we get 128.
Include the next digit (9) from the dividend after 128, then repeat: 1289 / 397

Moving on to step 8:
397 can be fit into 1289 3 times, resulting in a remainder of 98.
The next digit of our result is 3. 
Result so far: 212853.0
The remainder is 98 after subtracting 1191 from 1289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 9:
397 can be fit into 980 2 times, resulting in a remainder of 186.
Write down 2 as next digit of the result. 
Result so far: 212853.2
Subtracting 794 from 980 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 10:
1860 divided by 397 is 4 with a remainder of 272.
Use 4 as the next digit of our solution. 
Result so far: 212853.24
Subtracting 1588 from 1860 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 11:
397 can be fit into 2720 6 times, resulting in a remainder of 338.
The number 6 becomes the next digit in our result. 
Result so far: 212853.246
Deduct 2382 from 2720 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 12:
397 can be fit into 3380 8 times, resulting in a remainder of 204.
Put 8 as the next digit of the answer. 
Result so far: 212853.2468
Deduct 3176 from 3380 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 13:
When dividing 2040 by 397, we get 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 212853.24685
If we subtract 1985 from 2040, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 14:
When dividing 550 by 397, we get 1 with a remainder of 153.
Record the quotient 1 as the next digit in the result. 
Result so far: 212853.246851
Deduct 397 from 550 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 15:
If we divide 1530 by 397, we get 3 and a remainder of 339.
The next digit of our result is 3. 
Result so far: 212853.2468513
Deduct 1191 from 1530 and we're left with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Advancing to step 16:
If we divide 3390 by 397, we get 8 and a remainder of 214.
Use 8 as the next digit of our solution. 
Result so far: 212853.24685138
If we subtract 3176 from 3390, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

In conclusion, the division gives 212853.24685138 with a balance of 2.14e-07.
