We look at the division of 39693390 by 448 
We want to divide 39693390 by 448.

Going ahead to step 1:
448 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 448

On to step 2:
If we divide 39 by 448, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 448

On to step 3:
448 can be fit into 396 0 times, resulting in a remainder of 396.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 396, we get 396.
Include the next digit (9) from the dividend after 396, then repeat: 3969 / 448

Moving on to step 4:
When dividing 3969 by 448, we get 8 with a remainder of 385.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 3584 from 3969, we get 385.
Append the next digit (3) from the dividend to 385 and continue with: 3853 / 448

Advancing to step 5:
448 can be fit into 3853 8 times, resulting in a remainder of 269.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Deduct 3584 from 3853 and we're left with 269.
Bring next digit (3) of the dividend behind the 269 and repeat the process: 2693 / 448

On to step 6:
448 goes into 2693 6 times with a remainder of 5.
The next digit of our result is 6. 
Result so far: 886.0
If we take 2688 away from 2693, we end up with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 448

Advancing to step 7:
448 goes into 59 0 times with a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 8860.0
The remainder is 59 after subtracting 0 from 59.
Bring next digit (0) of the dividend behind the 59 and repeat the process: 590 / 448

Let's proceed to step 8:
When dividing 590 by 448, we get 1 with a remainder of 142.
Write down 1 as next digit of the result. 
Result so far: 88601.0
Deduct 448 from 590 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 9:
1420 divided by 448 is 3 with a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 88601.3
Subtract 1344 from 1420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
448 goes into 760 1 times with a remainder of 312.
The next digit of our result is 1. 
Result so far: 88601.31
If we subtract 448 from 760, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 11:
If we divide 3120 by 448, we get 6 and a remainder of 432.
Put 6 as the next digit of the answer. 
Result so far: 88601.316
Deduct 2688 from 3120 and we're left 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.

Going ahead to step 12:
The number 448 fits into 4320 9 times, leaving a remainder of 288.
Put 9 as the next digit of the answer. 
Result so far: 88601.3169
If we take 4032 away from 4320, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 13:
When dividing 2880 by 448, we get 6 with a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 88601.31696
If we subtract 2688 from 2880, we get 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 14:
If we divide 1920 by 448, we get 4 and a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 88601.316964
The remainder is 128 after subtracting 1792 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 15:
If we divide 1280 by 448, we get 2 and a remainder of 384.
Put 2 as the next digit of the answer. 
Result so far: 88601.3169642
The remainder is 384 after subtracting 896 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 16:
The number 448 fits into 3840 8 times, leaving a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 88601.31696428
Subtract 3584 from 3840 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Our division results in 88601.31696428 with a remaining 2.56e-07.
