31211533 ÷ 70 
We want to divide 31211533 by 70.

Let's proceed to step 1:
The number 70 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 70

Moving on to step 2:
31 divided by 70 is 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 70

On to step 3:
70 goes into 312 4 times with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 32 after subtracting 280 from 312.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 70

Going ahead to step 4:
70 can be fit into 321 4 times, resulting in a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we subtract 280 from 321, we get 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 70

On to step 5:
411 divided by 70 is 5 with a remainder of 61.
The next digit of our result is 5. 
Result so far: 445.0
Subtract 350 from 411 to get 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 70

Moving on to step 6:
70 goes into 615 8 times with a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 4458.0
If we take 560 away from 615, we end up with 55.
Take the next digit (3) from the dividend and append it to 55, then repeat: 553 / 70

Moving on to step 7:
70 can be fit into 553 7 times, resulting in a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 44587.0
Deduct 490 from 553 and we're left with 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 70

Moving on to step 8:
When dividing 633 by 70, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 445879.0
Deduct 630 from 633 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
30 divided by 70 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 445879.0
If we subtract 0 from 30, we get 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:
When dividing 300 by 70, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 445879.04
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
If we divide 200 by 70, we get 2 and a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 445879.042
Deduct 140 from 200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
If we divide 600 by 70, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 445879.0428
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
When dividing 400 by 70, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 445879.04285
If we subtract 350 from 400, 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:
When dividing 500 by 70, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 445879.042857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 15:
70 goes into 100 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 445879.0428571
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 16:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 445879.04285714
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 445879.04285714 with a balance of 2e-08.
