90435494 ÷ 972 
We want to divide 90435494 by 972.

Moving on to step 1:
When dividing 9 by 972, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 972

Advancing to step 2:
972 goes into 90 0 times with 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.
Bring next digit (4) of the dividend behind the 90 and repeat the process: 904 / 972

Step 3:
When dividing 904 by 972, we get 0 with a remainder of 904.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 904 to get 904.
Append the next digit (3) from the dividend to 904 and continue with: 9043 / 972

Moving on to step 4:
9043 divided by 972 is 9 with a remainder of 295.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 295 after subtracting 8748 from 9043.
Include the next digit (5) from the dividend after 295, then repeat: 2955 / 972

Going ahead to step 5:
2955 divided by 972 is 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Subtracting 2916 from 2955 leaves us with 39.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 972

Moving on to step 6:
394 divided by 972 is 0 with a remainder of 394.
The number 0 becomes the next digit in our result. 
Result so far: 930.0
Subtracting 0 from 394 leaves us with 394.
Include the next digit (9) from the dividend after 394, then repeat: 3949 / 972

Going ahead to step 7:
972 can be fit into 3949 4 times, resulting in a remainder of 61.
Record the quotient 4 as the next digit in the result. 
Result so far: 9304.0
If we subtract 3888 from 3949, we get 61.
Append the next digit (4) from the dividend to 61 and continue with: 614 / 972

Step 8:
614 divided by 972 is 0 with a remainder of 614.
Put 0 as the next digit of the answer. 
Result so far: 93040.0
Subtracting 0 from 614 leaves us with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Let's proceed to step 9:
972 goes into 6140 6 times with a remainder of 308.
Put 6 as the next digit of the answer. 
Result so far: 93040.6
Deduct 5832 from 6140 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 10:
972 goes into 3080 3 times with a remainder of 164.
The next digit of our result is 3. 
Result so far: 93040.63
Subtracting 2916 from 3080 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 11:
972 can be fit into 1640 1 times, resulting in a remainder of 668.
The next digit of our result is 1. 
Result so far: 93040.631
Subtracting 972 from 1640 leaves us with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Step 12:
6680 divided by 972 is 6 with a remainder of 848.
Put 6 as the next digit of the answer. 
Result so far: 93040.6316
The remainder is 848 after subtracting 5832 from 6680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Let's proceed to step 13:
When dividing 8480 by 972, we get 8 with a remainder of 704.
Use 8 as the next digit of our solution. 
Result so far: 93040.63168
Subtract 7776 from 8480 to get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Moving on to step 14:
The number 972 fits into 7040 7 times, leaving a remainder of 236.
Put 7 as the next digit of the answer. 
Result so far: 93040.631687
If we subtract 6804 from 7040, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 15:
The number 972 fits into 2360 2 times, leaving a remainder of 416.
Put 2 as the next digit of the answer. 
Result so far: 93040.6316872
If we subtract 1944 from 2360, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 16:
The number 972 fits into 4160 4 times, leaving a remainder of 272.
Put 4 as the next digit of the answer. 
Result so far: 93040.63168724
Subtract 3888 from 4160 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The final outcome is 93040.63168724, with a leftover of 2.72e-07.
