We're dividing 90840502 by 849 
We want to figure out the number of times 90840502 can be divided by 849.

Step 1:
If we divide 9 by 849, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 849

Advancing to step 2:
849 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Append the next digit (8) from the dividend to 90 and continue with: 908 / 849

On to step 3:
908 divided by 849 is 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 849 from 908 and we're left with 59.
Take the next digit (4) from the dividend and append it to 59, then repeat: 594 / 849

Advancing to step 4:
594 divided by 849 is 0 with a remainder of 594.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 594 and we're left with 594.
Include the next digit (0) from the dividend after 594, then repeat: 5940 / 849

Advancing to step 5:
5940 divided by 849 is 6 with a remainder of 846.
Write down 6 as next digit of the result. 
Result so far: 106.0
If we subtract 5094 from 5940, we get 846.
Include the next digit (5) from the dividend after 846, then repeat: 8465 / 849

Step 6:
8465 divided by 849 is 9 with a remainder of 824.
Record the quotient 9 as the next digit in the result. 
Result so far: 1069.0
If we subtract 7641 from 8465, we get 824.
Grab the next digit (0) from the dividend, add it to 824, then carry on: 8240 / 849

Going ahead to step 7:
When dividing 8240 by 849, we get 9 with a remainder of 599.
Write down 9 as next digit of the result. 
Result so far: 10699.0
Deduct 7641 from 8240 and we're left with 599.
Grab the next digit (2) from the dividend, add it to 599, then carry on: 5992 / 849

Step 8:
849 goes into 5992 7 times with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 106997.0
If we subtract 5943 from 5992, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
If we divide 490 by 849, we get 0 and a remainder of 490.
Write down 0 as next digit of the result. 
Result so far: 106997.0
If we take 0 away from 490, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 10:
849 can be fit into 4900 5 times, resulting in a remainder of 655.
The next digit of our result is 5. 
Result so far: 106997.05
Subtracting 4245 from 4900 leaves us with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Step 11:
6550 divided by 849 is 7 with a remainder of 607.
Write down 7 as next digit of the result. 
Result so far: 106997.057
The remainder is 607 after subtracting 5943 from 6550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Advancing to step 12:
849 goes into 6070 7 times with a remainder of 127.
Put 7 as the next digit of the answer. 
Result so far: 106997.0577
Deduct 5943 from 6070 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

The quotient of the division is 106997.0577, and the remainder is 0.00127.
