We're dividing 90464100 by 744 
We want to figure out the number of times 90464100 can be divided by 744.

Let's proceed to step 1:
If we divide 9 by 744, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 744

Let's proceed to step 2:
744 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
Subtracting 0 from 90 leaves us with 90.
Bring next digit (4) of the dividend behind the 90 and repeat the process: 904 / 744

Step 3:
904 divided by 744 is 1 with a remainder of 160.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 744 from 904, we get 160.
Bring next digit (6) of the dividend behind the 160 and repeat the process: 1606 / 744

Let's proceed to step 4:
When dividing 1606 by 744, we get 2 with a remainder of 118.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1488 from 1606, we get 118.
Grab the next digit (4) from the dividend, add it to 118, then carry on: 1184 / 744

On to step 5:
If we divide 1184 by 744, we get 1 and a remainder of 440.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtract 744 from 1184 to get 440.
Fetch the next digit (1) from the dividend, attach it to 440 and continue: 4401 / 744

Going ahead to step 6:
744 can be fit into 4401 5 times, resulting in a remainder of 681.
Put 5 as the next digit of the answer. 
Result so far: 1215.0
Deduct 3720 from 4401 and we're left with 681.
Bring next digit (0) of the dividend behind the 681 and repeat the process: 6810 / 744

Advancing to step 7:
The number 744 fits into 6810 9 times, leaving a remainder of 114.
The next digit of our result is 9. 
Result so far: 12159.0
If we subtract 6696 from 6810, we get 114.
Grab the next digit (0) from the dividend, add it to 114, then carry on: 1140 / 744

On to step 8:
744 can be fit into 1140 1 times, resulting in a remainder of 396.
Put 1 as the next digit of the answer. 
Result so far: 121591.0
Deduct 744 from 1140 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 9:
When dividing 3960 by 744, we get 5 with a remainder of 240.
Record the quotient 5 as the next digit in the result. 
Result so far: 121591.5
If we subtract 3720 from 3960, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 10:
744 goes into 2400 3 times with a remainder of 168.
Record the quotient 3 as the next digit in the result. 
Result so far: 121591.53
If we take 2232 away from 2400, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 11:
744 goes into 1680 2 times with a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 121591.532
Deduct 1488 from 1680 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 12:
744 can be fit into 1920 2 times, resulting in a remainder of 432.
Use 2 as the next digit of our solution. 
Result so far: 121591.5322
Subtracting 1488 from 1920 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.

The quotient of the division is 121591.5322, and the remainder is 0.00432.
