We look at the division of 45153837 by 448 
We want to figure out the number of times 45153837 can be divided by 448.

Advancing to step 1:
448 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 448

Let's proceed to step 2:
The number 448 fits into 45 0 times, leaving a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 448

Step 3:
448 goes into 451 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 448 from 451 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 448

On to step 4:
If we divide 35 by 448, we get 0 and a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 448

Let's proceed to step 5:
448 goes into 353 0 times with a remainder of 353.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we subtract 0 from 353, we get 353.
Grab the next digit (8) from the dividend, add it to 353, then carry on: 3538 / 448

Moving on to step 6:
If we divide 3538 by 448, we get 7 and a remainder of 402.
Use 7 as the next digit of our solution. 
Result so far: 1007.0
If we take 3136 away from 3538, we end up with 402.
Grab the next digit (3) from the dividend, add it to 402, then carry on: 4023 / 448

On to step 7:
448 goes into 4023 8 times with a remainder of 439.
Use 8 as the next digit of our solution. 
Result so far: 10078.0
If we subtract 3584 from 4023, we get 439.
Grab the next digit (7) from the dividend, add it to 439, then carry on: 4397 / 448

Step 8:
If we divide 4397 by 448, we get 9 and a remainder of 365.
Put 9 as the next digit of the answer. 
Result so far: 100789.0
Subtracting 4032 from 4397 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 9:
When dividing 3650 by 448, we get 8 with a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 100789.8
If we subtract 3584 from 3650, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
448 can be fit into 660 1 times, resulting in a remainder of 212.
The number 1 becomes the next digit in our result. 
Result so far: 100789.81
Subtract 448 from 660 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 11:
If we divide 2120 by 448, we get 4 and a remainder of 328.
The next digit of our result is 4. 
Result so far: 100789.814
If we subtract 1792 from 2120, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 12:
When dividing 3280 by 448, we get 7 with a remainder of 144.
Use 7 as the next digit of our solution. 
Result so far: 100789.8147
Subtracting 3136 from 3280 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 13:
When dividing 1440 by 448, we get 3 with a remainder of 96.
Put 3 as the next digit of the answer. 
Result so far: 100789.81473
Deduct 1344 from 1440 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 14:
The number 448 fits into 960 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 100789.814732
Subtracting 896 from 960 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
448 can be fit into 640 1 times, resulting in a remainder of 192.
Use 1 as the next digit of our solution. 
Result so far: 100789.8147321
If we subtract 448 from 640, 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.

On to step 16:
448 goes into 1920 4 times with a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 100789.81473214
Subtract 1792 from 1920 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 100789.81473214 with a remainder of 1.28e-07.
