901668 ÷ 70 
We're looking to find how many times 70 goes into 901668.

Step 1:
If we divide 9 by 70, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 70

Going ahead to step 2:
When dividing 90 by 70, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 70 from 90, we get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 70

Advancing to step 3:
70 goes into 201 2 times with a remainder of 61.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 140 from 201, we get 61.
Bring next digit (6) of the dividend behind the 61 and repeat the process: 616 / 70

Advancing to step 4:
The number 70 fits into 616 8 times, leaving a remainder of 56.
The next digit of our result is 8. 
Result so far: 128.0
Subtracting 560 from 616 leaves us with 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 70

Let's proceed to step 5:
566 divided by 70 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 1288.0
If we take 560 away from 566, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 70

Let's proceed to step 6:
The number 70 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 12880.0
The remainder is 68 after subtracting 0 from 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
70 goes into 680 9 times with a remainder of 50.
The number 9 becomes the next digit in our result. 
Result so far: 12880.9
The remainder is 50 after subtracting 630 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
If we divide 500 by 70, we get 7 and a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 12880.97
Deduct 490 from 500 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
100 divided by 70 is 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 12880.971
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.

Advancing to step 10:
300 divided by 70 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 12880.9714
If we take 280 away from 300, we end up 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.

Step 11:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The next digit of our result is 2. 
Result so far: 12880.97142
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.

Let's proceed to step 12:
When dividing 600 by 70, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 12880.971428
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
400 divided by 70 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 12880.9714285
Deduct 350 from 400 and we're left with 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:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 12880.97142857
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.

The final outcome is 12880.97142857, with a leftover of 1e-08.
