670161 ÷ 70 
We're looking to find how many times 70 goes into 670161.

Going ahead to step 1:
When dividing 6 by 70, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 70

On to step 2:
70 goes into 67 0 times with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 70

Moving on to step 3:
If we divide 670 by 70, we get 9 and a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 40 after subtracting 630 from 670.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 70

Step 4:
If we divide 401 by 70, we get 5 and a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Subtracting 350 from 401 leaves us with 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 70

On to step 5:
70 goes into 516 7 times with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 957.0
Subtracting 490 from 516 leaves us with 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 70

Let's proceed to step 6:
If we divide 261 by 70, we get 3 and a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 9573.0
Subtracting 210 from 261 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
510 divided by 70 is 7 with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 9573.7
Deduct 490 from 510 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.

Let's proceed to step 8:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 9573.72
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
When dividing 600 by 70, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 9573.728
Deduct 560 from 600 and we're left 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 10:
70 goes into 400 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 9573.7285
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.

On to step 11:
500 divided by 70 is 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 9573.72857
If we subtract 490 from 500, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 9573.728571
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.

Step 13:
70 goes into 300 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 9573.7285714
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.

Let's proceed to step 14:
70 goes into 200 2 times with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 9573.72857142
If we take 140 away from 200, we end up 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.

The final result is 9573.72857142 with a remainder of 6e-08.
