70059902 ÷ 450 
We want to divide 70059902 by 450.

Let's proceed to step 1:
450 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 450

Advancing to step 2:
70 divided by 450 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 450

Let's proceed to step 3:
450 goes into 700 1 times with a remainder of 250.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 450 from 700 to get 250.
Take the next digit (5) from the dividend and append it to 250, then repeat: 2505 / 450

On to step 4:
When dividing 2505 by 450, we get 5 with a remainder of 255.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 255 after subtracting 2250 from 2505.
Fetch the next digit (9) from the dividend, attach it to 255 and continue: 2559 / 450

On to step 5:
The number 450 fits into 2559 5 times, leaving a remainder of 309.
Write down 5 as next digit of the result. 
Result so far: 155.0
Deduct 2250 from 2559 and we're left with 309.
Fetch the next digit (9) from the dividend, attach it to 309 and continue: 3099 / 450

Going ahead to step 6:
450 can be fit into 3099 6 times, resulting in a remainder of 399.
Record the quotient 6 as the next digit in the result. 
Result so far: 1556.0
Deduct 2700 from 3099 and we're left with 399.
Fetch the next digit (0) from the dividend, attach it to 399 and continue: 3990 / 450

Let's proceed to step 7:
3990 divided by 450 is 8 with a remainder of 390.
Use 8 as the next digit of our solution. 
Result so far: 15568.0
The remainder is 390 after subtracting 3600 from 3990.
Take the next digit (2) from the dividend and append it to 390, then repeat: 3902 / 450

On to step 8:
If we divide 3902 by 450, we get 8 and a remainder of 302.
Use 8 as the next digit of our solution. 
Result so far: 155688.0
If we take 3600 away from 3902, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 9:
3020 divided by 450 is 6 with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 155688.6
Subtracting 2700 from 3020 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 10:
If we divide 3200 by 450, we get 7 and a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 155688.67
Deduct 3150 from 3200 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
500 divided by 450 is 1 with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 155688.671
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.

Let's proceed to step 12:
450 goes into 500 1 times with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 155688.6711
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 155688.6711 with a balance of 0.0005.
