We're dividing 90612148 by 810 
We want to divide 90612148 by 810.

Going ahead to step 1:
When dividing 9 by 810, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 810

Let's proceed to step 2:
810 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Bring next digit (6) of the dividend behind the 90 and repeat the process: 906 / 810

Moving on to step 3:
810 can be fit into 906 1 times, resulting in a remainder of 96.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 810 away from 906, we end up with 96.
Fetch the next digit (1) from the dividend, attach it to 96 and continue: 961 / 810

Let's proceed to step 4:
If we divide 961 by 810, we get 1 and a remainder of 151.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 151 after subtracting 810 from 961.
Append the next digit (2) from the dividend to 151 and continue with: 1512 / 810

On to step 5:
The number 810 fits into 1512 1 times, leaving a remainder of 702.
Write down 1 as next digit of the result. 
Result so far: 111.0
The remainder is 702 after subtracting 810 from 1512.
Grab the next digit (1) from the dividend, add it to 702, then carry on: 7021 / 810

On to step 6:
810 can be fit into 7021 8 times, resulting in a remainder of 541.
Use 8 as the next digit of our solution. 
Result so far: 1118.0
Subtract 6480 from 7021 to get 541.
Fetch the next digit (4) from the dividend, attach it to 541 and continue: 5414 / 810

Let's proceed to step 7:
810 can be fit into 5414 6 times, resulting in a remainder of 554.
Record the quotient 6 as the next digit in the result. 
Result so far: 11186.0
Subtract 4860 from 5414 to get 554.
Fetch the next digit (8) from the dividend, attach it to 554 and continue: 5548 / 810

Advancing to step 8:
810 can be fit into 5548 6 times, resulting in a remainder of 688.
Put 6 as the next digit of the answer. 
Result so far: 111866.0
If we subtract 4860 from 5548, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Let's proceed to step 9:
When dividing 6880 by 810, we get 8 with a remainder of 400.
The next digit of our result is 8. 
Result so far: 111866.8
Deduct 6480 from 6880 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 10:
4000 divided by 810 is 4 with a remainder of 760.
Write down 4 as next digit of the result. 
Result so far: 111866.84
If we subtract 3240 from 4000, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 11:
The number 810 fits into 7600 9 times, leaving a remainder of 310.
Use 9 as the next digit of our solution. 
Result so far: 111866.849
Deduct 7290 from 7600 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 12:
3100 divided by 810 is 3 with a remainder of 670.
Record the quotient 3 as the next digit in the result. 
Result so far: 111866.8493
If we subtract 2430 from 3100, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 13:
When dividing 6700 by 810, we get 8 with a remainder of 220.
Use 8 as the next digit of our solution. 
Result so far: 111866.84938
Deduct 6480 from 6700 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 14:
2200 divided by 810 is 2 with a remainder of 580.
The next digit of our result is 2. 
Result so far: 111866.849382
If we take 1620 away from 2200, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 15:
When dividing 5800 by 810, we get 7 with a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 111866.8493827
Deduct 5670 from 5800 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 16:
The number 810 fits into 1300 1 times, leaving a remainder of 490.
Write down 1 as next digit of the result. 
Result so far: 111866.84938271
If we subtract 810 from 1300, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

The final result is 111866.84938271 with a remainder of 4.9e-07.
