70289870 divided by 450 
Our goal is to divide 70289870 by 450.

Moving on to step 1:
If we divide 7 by 450, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 450

Going ahead to step 2:
If we divide 70 by 450, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Take the next digit (2) from the dividend and append it to 70, then repeat: 702 / 450

On to step 3:
If we divide 702 by 450, we get 1 and a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 450 from 702 and we're left with 252.
Fetch the next digit (8) from the dividend, attach it to 252 and continue: 2528 / 450

Advancing to step 4:
2528 divided by 450 is 5 with a remainder of 278.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 2250 from 2528 leaves us with 278.
Append the next digit (9) from the dividend to 278 and continue with: 2789 / 450

On to step 5:
The number 450 fits into 2789 6 times, leaving a remainder of 89.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
Subtracting 2700 from 2789 leaves us with 89.
Take the next digit (8) from the dividend and append it to 89, then repeat: 898 / 450

Advancing to step 6:
450 goes into 898 1 times with a remainder of 448.
The next digit of our result is 1. 
Result so far: 1561.0
Deduct 450 from 898 and we're left with 448.
Grab the next digit (7) from the dividend, add it to 448, then carry on: 4487 / 450

On to step 7:
The number 450 fits into 4487 9 times, leaving a remainder of 437.
Record the quotient 9 as the next digit in the result. 
Result so far: 15619.0
Deduct 4050 from 4487 and we're left with 437.
Take the next digit (0) from the dividend and append it to 437, then repeat: 4370 / 450

Let's proceed to step 8:
When dividing 4370 by 450, we get 9 with a remainder of 320.
Use 9 as the next digit of our solution. 
Result so far: 156199.0
If we subtract 4050 from 4370, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 9:
450 can be fit into 3200 7 times, resulting in a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 156199.7
Subtract 3150 from 3200 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
The number 450 fits into 500 1 times, leaving a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 156199.71
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
When dividing 500 by 450, we get 1 with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 156199.711
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 156199.711 and a remainder of 0.005.
