45071485 ÷ 850 
Our goal is to divide 45071485 by 850.

Going ahead to step 1:
The number 850 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
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 / 850

On to step 2:
45 divided by 850 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 850

Step 3:
450 divided by 850 is 0 with a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 450 and we're left with 450.
Bring next digit (7) of the dividend behind the 450 and repeat the process: 4507 / 850

Advancing to step 4:
850 goes into 4507 5 times with a remainder of 257.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 4250 away from 4507, we end up with 257.
Fetch the next digit (1) from the dividend, attach it to 257 and continue: 2571 / 850

Step 5:
2571 divided by 850 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtracting 2550 from 2571 leaves us with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 850

Step 6:
850 goes into 214 0 times with a remainder of 214.
Use 0 as the next digit of our solution. 
Result so far: 530.0
If we take 0 away from 214, we end up with 214.
Take the next digit (8) from the dividend and append it to 214, then repeat: 2148 / 850

On to step 7:
The number 850 fits into 2148 2 times, leaving a remainder of 448.
The next digit of our result is 2. 
Result so far: 5302.0
Subtracting 1700 from 2148 leaves us with 448.
Bring next digit (5) of the dividend behind the 448 and repeat the process: 4485 / 850

Going ahead to step 8:
850 can be fit into 4485 5 times, resulting in a remainder of 235.
The next digit of our result is 5. 
Result so far: 53025.0
Subtract 4250 from 4485 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 9:
If we divide 2350 by 850, we get 2 and a remainder of 650.
Use 2 as the next digit of our solution. 
Result so far: 53025.2
If we subtract 1700 from 2350, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 10:
When dividing 6500 by 850, we get 7 with a remainder of 550.
Record the quotient 7 as the next digit in the result. 
Result so far: 53025.27
If we subtract 5950 from 6500, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 11:
850 can be fit into 5500 6 times, resulting in a remainder of 400.
The next digit of our result is 6. 
Result so far: 53025.276
If we subtract 5100 from 5500, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 12:
The number 850 fits into 4000 4 times, leaving a remainder of 600.
Write down 4 as next digit of the result. 
Result so far: 53025.2764
Deduct 3400 from 4000 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 13:
If we divide 6000 by 850, we get 7 and a remainder of 50.
The next digit of our result is 7. 
Result so far: 53025.27647
If we subtract 5950 from 6000, 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.

Advancing to step 14:
The number 850 fits into 500 0 times, leaving a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 53025.27647
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 15:
850 can be fit into 5000 5 times, resulting in a remainder of 750.
Record the quotient 5 as the next digit in the result. 
Result so far: 53025.2764705
Deduct 4250 from 5000 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 16:
7500 divided by 850 is 8 with a remainder of 700.
Put 8 as the next digit of the answer. 
Result so far: 53025.27647058
If we subtract 6800 from 7500, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final result is 53025.27647058 with a remainder of 7e-07.
