We divide 99428087 by 581
Our goal is to divide 99428087 by 581.

Advancing to step 1:
When dividing 9 by 581, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 581

Step 2:
If we divide 99 by 581, we get 0 and a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Take the next digit (4) from the dividend and append it to 99, then repeat: 994 / 581

Going ahead to step 3:
The number 581 fits into 994 1 times, leaving a remainder of 413.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 581 from 994 and we're left with 413.
Grab the next digit (2) from the dividend, add it to 413, then carry on: 4132 / 581

Let's proceed to step 4:
When dividing 4132 by 581, we get 7 with a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 4067 from 4132 to get 65.
Take the next digit (8) from the dividend and append it to 65, then repeat: 658 / 581

On to step 5:
If we divide 658 by 581, we get 1 and a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 171.0
Subtract 581 from 658 to get 77.
Append the next digit (0) from the dividend to 77 and continue with: 770 / 581

On to step 6:
The number 581 fits into 770 1 times, leaving a remainder of 189.
Record the quotient 1 as the next digit in the result. 
Result so far: 1711.0
Subtract 581 from 770 to get 189.
Grab the next digit (8) from the dividend, add it to 189, then carry on: 1898 / 581

Going ahead to step 7:
When dividing 1898 by 581, we get 3 with a remainder of 155.
Put 3 as the next digit of the answer. 
Result so far: 17113.0
The remainder is 155 after subtracting 1743 from 1898.
Grab the next digit (7) from the dividend, add it to 155, then carry on: 1557 / 581

On to step 8:
The number 581 fits into 1557 2 times, leaving a remainder of 395.
Use 2 as the next digit of our solution. 
Result so far: 171132.0
The remainder is 395 after subtracting 1162 from 1557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 9:
581 can be fit into 3950 6 times, resulting in a remainder of 464.
Use 6 as the next digit of our solution. 
Result so far: 171132.6
If we take 3486 away from 3950, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 10:
When dividing 4640 by 581, we get 7 with a remainder of 573.
Put 7 as the next digit of the answer. 
Result so far: 171132.67
If we subtract 4067 from 4640, we get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Advancing to step 11:
5730 divided by 581 is 9 with a remainder of 501.
The next digit of our result is 9. 
Result so far: 171132.679
Subtract 5229 from 5730 to get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

On to step 12:
When dividing 5010 by 581, we get 8 with a remainder of 362.
Use 8 as the next digit of our solution. 
Result so far: 171132.6798
If we subtract 4648 from 5010, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

On to step 13:
If we divide 3620 by 581, we get 6 and a remainder of 134.
Write down 6 as next digit of the result. 
Result so far: 171132.67986
Subtracting 3486 from 3620 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 14:
The number 581 fits into 1340 2 times, leaving a remainder of 178.
Use 2 as the next digit of our solution. 
Result so far: 171132.679862
Subtracting 1162 from 1340 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 15:
581 goes into 1780 3 times with a remainder of 37.
The next digit of our result is 3. 
Result so far: 171132.6798623
Subtract 1743 from 1780 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 16:
When dividing 370 by 581, we get 0 with a remainder of 370.
The next digit of our result is 0. 
Result so far: 171132.6798623
Deduct 0 from 370 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The quotient of the division is 171132.6798623, and the remainder is 3.7e-07.
