We look at the division of 70355386 by 289 
We want to figure out the number of times 70355386 can be divided by 289.

On to step 1:
7 divided by 289 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 289

Going ahead to step 2:
The number 289 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 289

Let's proceed to step 3:
When dividing 703 by 289, we get 2 with a remainder of 125.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 578 from 703 and we're left with 125.
Bring next digit (5) of the dividend behind the 125 and repeat the process: 1255 / 289

Advancing to step 4:
If we divide 1255 by 289, we get 4 and a remainder of 99.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 99 after subtracting 1156 from 1255.
Bring next digit (5) of the dividend behind the 99 and repeat the process: 995 / 289

Advancing to step 5:
If we divide 995 by 289, we get 3 and a remainder of 128.
Use 3 as the next digit of our solution. 
Result so far: 243.0
Subtract 867 from 995 to get 128.
Bring next digit (3) of the dividend behind the 128 and repeat the process: 1283 / 289

Going ahead to step 6:
289 goes into 1283 4 times with a remainder of 127.
The number 4 becomes the next digit in our result. 
Result so far: 2434.0
Deduct 1156 from 1283 and we're left with 127.
Fetch the next digit (8) from the dividend, attach it to 127 and continue: 1278 / 289

On to step 7:
289 goes into 1278 4 times with a remainder of 122.
The number 4 becomes the next digit in our result. 
Result so far: 24344.0
The remainder is 122 after subtracting 1156 from 1278.
Grab the next digit (6) from the dividend, add it to 122, then carry on: 1226 / 289

Advancing to step 8:
The number 289 fits into 1226 4 times, leaving a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 243444.0
If we subtract 1156 from 1226, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
700 divided by 289 is 2 with a remainder of 122.
Write down 2 as next digit of the result. 
Result so far: 243444.2
If we take 578 away from 700, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 10:
289 can be fit into 1220 4 times, resulting in a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 243444.24
Subtract 1156 from 1220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
When dividing 640 by 289, we get 2 with a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 243444.242
Subtract 578 from 640 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 12:
When dividing 620 by 289, we get 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 243444.2422
Subtract 578 from 620 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 243444.2422 and a remainder of 0.00042.
