Let's divide 85293710 by 990
We're looking to find how many times 990 goes into 85293710.

Going ahead to step 1:
8 divided by 990 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 990

On to step 2:
The number 990 fits into 85 0 times, leaving a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Append the next digit (2) from the dividend to 85 and continue with: 852 / 990

Let's proceed to step 3:
If we divide 852 by 990, we get 0 and a remainder of 852.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 852 after subtracting 0 from 852.
Bring next digit (9) of the dividend behind the 852 and repeat the process: 8529 / 990

Let's proceed to step 4:
990 goes into 8529 8 times with a remainder of 609.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 7920 from 8529 to get 609.
Fetch the next digit (3) from the dividend, attach it to 609 and continue: 6093 / 990

Step 5:
990 can be fit into 6093 6 times, resulting in a remainder of 153.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Deduct 5940 from 6093 and we're left with 153.
Take the next digit (7) from the dividend and append it to 153, then repeat: 1537 / 990

Going ahead to step 6:
990 goes into 1537 1 times with a remainder of 547.
Write down 1 as next digit of the result. 
Result so far: 861.0
Deduct 990 from 1537 and we're left with 547.
Grab the next digit (1) from the dividend, add it to 547, then carry on: 5471 / 990

On to step 7:
990 can be fit into 5471 5 times, resulting in a remainder of 521.
Use 5 as the next digit of our solution. 
Result so far: 8615.0
Subtract 4950 from 5471 to get 521.
Append the next digit (0) from the dividend to 521 and continue with: 5210 / 990

Advancing to step 8:
990 goes into 5210 5 times with a remainder of 260.
The number 5 becomes the next digit in our result. 
Result so far: 86155.0
Deduct 4950 from 5210 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 9:
When dividing 2600 by 990, we get 2 with a remainder of 620.
Put 2 as the next digit of the answer. 
Result so far: 86155.2
Deduct 1980 from 2600 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 10:
990 can be fit into 6200 6 times, resulting in a remainder of 260.
The number 6 becomes the next digit in our result. 
Result so far: 86155.26
If we subtract 5940 from 6200, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
990 goes into 2600 2 times with a remainder of 620.
The next digit of our result is 2. 
Result so far: 86155.262
Subtract 1980 from 2600 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 12:
6200 divided by 990 is 6 with a remainder of 260.
Use 6 as the next digit of our solution. 
Result so far: 86155.2626
Subtract 5940 from 6200 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 13:
990 goes into 2600 2 times with a remainder of 620.
Write down 2 as next digit of the result. 
Result so far: 86155.26262
Subtract 1980 from 2600 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 14:
If we divide 6200 by 990, we get 6 and a remainder of 260.
The number 6 becomes the next digit in our result. 
Result so far: 86155.262626
The remainder is 260 after subtracting 5940 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 15:
The number 990 fits into 2600 2 times, leaving a remainder of 620.
Put 2 as the next digit of the answer. 
Result so far: 86155.2626262
Deduct 1980 from 2600 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 16:
990 goes into 6200 6 times with a remainder of 260.
Put 6 as the next digit of the answer. 
Result so far: 86155.26262626
Subtract 5940 from 6200 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

In conclusion, the division gives 86155.26262626 with a balance of 2.6e-07.
