81994597 divided by 389 
We want to figure out the number of times 81994597 can be divided by 389.

Advancing to step 1:
389 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 389

Advancing to step 2:
The number 389 fits into 81 0 times, leaving a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Grab the next digit (9) from the dividend, add it to 81, then carry on: 819 / 389

Advancing to step 3:
The number 389 fits into 819 2 times, leaving a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 778 from 819 and we're left with 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 389

Moving on to step 4:
389 can be fit into 419 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 389 away from 419, we end up with 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 389

Going ahead to step 5:
304 divided by 389 is 0 with a remainder of 304.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
Deduct 0 from 304 and we're left with 304.
Bring next digit (5) of the dividend behind the 304 and repeat the process: 3045 / 389

Moving on to step 6:
389 goes into 3045 7 times with a remainder of 322.
Record the quotient 7 as the next digit in the result. 
Result so far: 2107.0
If we subtract 2723 from 3045, we get 322.
Grab the next digit (9) from the dividend, add it to 322, then carry on: 3229 / 389

Step 7:
If we divide 3229 by 389, we get 8 and a remainder of 117.
Write down 8 as next digit of the result. 
Result so far: 21078.0
The remainder is 117 after subtracting 3112 from 3229.
Fetch the next digit (7) from the dividend, attach it to 117 and continue: 1177 / 389

On to step 8:
1177 divided by 389 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 210783.0
If we take 1167 away from 1177, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
389 goes into 100 0 times with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 210783.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 10:
If we divide 1000 by 389, we get 2 and a remainder of 222.
Use 2 as the next digit of our solution. 
Result so far: 210783.02
Deduct 778 from 1000 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 11:
If we divide 2220 by 389, we get 5 and a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 210783.025
If we subtract 1945 from 2220, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 12:
389 can be fit into 2750 7 times, resulting in a remainder of 27.
The next digit of our result is 7. 
Result so far: 210783.0257
If we subtract 2723 from 2750, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
When dividing 270 by 389, we get 0 with a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 210783.0257
Deduct 0 from 270 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 14:
389 goes into 2700 6 times with a remainder of 366.
Record the quotient 6 as the next digit in the result. 
Result so far: 210783.025706
Deduct 2334 from 2700 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 15:
389 goes into 3660 9 times with a remainder of 159.
The next digit of our result is 9. 
Result so far: 210783.0257069
If we subtract 3501 from 3660, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 16:
1590 divided by 389 is 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 210783.02570694
If we subtract 1556 from 1590, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 210783.02570694 with a remaining 3.4e-08.
