We divide 851998 by 70
We want to figure out the number of times 851998 can be divided by 70.

Moving on to step 1:
If we divide 8 by 70, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 70

Moving on to step 2:
The number 70 fits into 85 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 70 from 85 and we're left with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 70

Moving on to step 3:
When dividing 151 by 70, we get 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 12.0
If we take 140 away from 151, we end up with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 70

Moving on to step 4:
70 can be fit into 119 1 times, resulting in a remainder of 49.
The next digit of our result is 1. 
Result so far: 121.0
Subtracting 70 from 119 leaves us with 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 70

Let's proceed to step 5:
499 divided by 70 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 1217.0
The remainder is 9 after subtracting 490 from 499.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 70

Let's proceed to step 6:
70 goes into 98 1 times with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 12171.0
Deduct 70 from 98 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
70 can be fit into 280 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 12171.4
Subtracting 280 from 280 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
70 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12171.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
70 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12171.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 12171.4 with a remaining 0.0.
