We're dividing 70311219 by 160 
We want to figure out the number of times 70311219 can be divided by 160.

Let's proceed to step 1:
The number 160 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 160

Moving on to step 2:
160 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 160

Advancing to step 3:
If we divide 703 by 160, we get 4 and a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 640 away from 703, we end up with 63.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 160

Advancing to step 4:
631 divided by 160 is 3 with a remainder of 151.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we subtract 480 from 631, we get 151.
Fetch the next digit (1) from the dividend, attach it to 151 and continue: 1511 / 160

On to step 5:
The number 160 fits into 1511 9 times, leaving a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 439.0
Deduct 1440 from 1511 and we're left with 71.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 160

Going ahead to step 6:
160 goes into 712 4 times with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 4394.0
If we subtract 640 from 712, we get 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 160

Moving on to step 7:
160 can be fit into 721 4 times, resulting in a remainder of 81.
Put 4 as the next digit of the answer. 
Result so far: 43944.0
If we subtract 640 from 721, we get 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 160

On to step 8:
When dividing 819 by 160, we get 5 with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 439445.0
If we subtract 800 from 819, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
When dividing 190 by 160, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 439445.1
Deduct 160 from 190 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
160 goes into 300 1 times with a remainder of 140.
The next digit of our result is 1. 
Result so far: 439445.11
Deduct 160 from 300 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 439445.11, with a leftover of 0.14.
