Let's divide 90643761 by 849
We want to figure out the number of times 90643761 can be divided by 849.

Advancing to step 1:
849 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 849

Going ahead to step 2:
849 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Take the next digit (6) from the dividend and append it to 90, then repeat: 906 / 849

Advancing to step 3:
849 can be fit into 906 1 times, resulting in a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 849 away from 906, we end up with 57.
Bring next digit (4) of the dividend behind the 57 and repeat the process: 574 / 849

Step 4:
849 goes into 574 0 times with a remainder of 574.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 574, we get 574.
Append the next digit (3) from the dividend to 574 and continue with: 5743 / 849

Going ahead to step 5:
849 goes into 5743 6 times with a remainder of 649.
Write down 6 as next digit of the result. 
Result so far: 106.0
If we subtract 5094 from 5743, we get 649.
Take the next digit (7) from the dividend and append it to 649, then repeat: 6497 / 849

Advancing to step 6:
When dividing 6497 by 849, we get 7 with a remainder of 554.
Put 7 as the next digit of the answer. 
Result so far: 1067.0
The remainder is 554 after subtracting 5943 from 6497.
Grab the next digit (6) from the dividend, add it to 554, then carry on: 5546 / 849

Advancing to step 7:
849 can be fit into 5546 6 times, resulting in a remainder of 452.
The number 6 becomes the next digit in our result. 
Result so far: 10676.0
If we subtract 5094 from 5546, we get 452.
Include the next digit (1) from the dividend after 452, then repeat: 4521 / 849

Going ahead to step 8:
When dividing 4521 by 849, we get 5 with a remainder of 276.
Use 5 as the next digit of our solution. 
Result so far: 106765.0
If we subtract 4245 from 4521, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 9:
When dividing 2760 by 849, we get 3 with a remainder of 213.
Write down 3 as next digit of the result. 
Result so far: 106765.3
Subtracting 2547 from 2760 leaves us with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Let's proceed to step 10:
849 goes into 2130 2 times with a remainder of 432.
Put 2 as the next digit of the answer. 
Result so far: 106765.32
Subtracting 1698 from 2130 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 11:
4320 divided by 849 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 106765.325
The remainder is 75 after subtracting 4245 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 12:
When dividing 750 by 849, we get 0 with a remainder of 750.
Use 0 as the next digit of our solution. 
Result so far: 106765.325
If we subtract 0 from 750, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Going ahead to step 13:
7500 divided by 849 is 8 with a remainder of 708.
Record the quotient 8 as the next digit in the result. 
Result so far: 106765.32508
Subtracting 6792 from 7500 leaves us with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Moving on to step 14:
7080 divided by 849 is 8 with a remainder of 288.
The next digit of our result is 8. 
Result so far: 106765.325088
Subtract 6792 from 7080 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The quotient of the division is 106765.325088, and the remainder is 2.88e-05.
