We look at the division of 70092961 by 640 
We want to figure out the number of times 70092961 can be divided by 640.

Step 1:
If we divide 7 by 640, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 640

On to step 2:
640 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 640

Moving on to step 3:
700 divided by 640 is 1 with a remainder of 60.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 640 from 700 and we're left with 60.
Take the next digit (9) from the dividend and append it to 60, then repeat: 609 / 640

Step 4:
The number 640 fits into 609 0 times, leaving a remainder of 609.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 609 and we're left with 609.
Grab the next digit (2) from the dividend, add it to 609, then carry on: 6092 / 640

On to step 5:
The number 640 fits into 6092 9 times, leaving a remainder of 332.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
The remainder is 332 after subtracting 5760 from 6092.
Append the next digit (9) from the dividend to 332 and continue with: 3329 / 640

On to step 6:
The number 640 fits into 3329 5 times, leaving a remainder of 129.
The next digit of our result is 5. 
Result so far: 1095.0
Subtracting 3200 from 3329 leaves us with 129.
Take the next digit (6) from the dividend and append it to 129, then repeat: 1296 / 640

Moving on to step 7:
640 can be fit into 1296 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 10952.0
If we subtract 1280 from 1296, we get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 640

Step 8:
When dividing 161 by 640, we get 0 with a remainder of 161.
Put 0 as the next digit of the answer. 
Result so far: 109520.0
The remainder is 161 after subtracting 0 from 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 9:
If we divide 1610 by 640, we get 2 and a remainder of 330.
Put 2 as the next digit of the answer. 
Result so far: 109520.2
If we subtract 1280 from 1610, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 10:
The number 640 fits into 3300 5 times, leaving a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 109520.25
Subtracting 3200 from 3300 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
The number 640 fits into 1000 1 times, leaving a remainder of 360.
Put 1 as the next digit of the answer. 
Result so far: 109520.251
The remainder is 360 after subtracting 640 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 12:
640 goes into 3600 5 times with a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 109520.2515
If we subtract 3200 from 3600, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
If we divide 4000 by 640, we get 6 and a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 109520.25156
The remainder is 160 after subtracting 3840 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
1600 divided by 640 is 2 with a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 109520.251562
Subtracting 1280 from 1600 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
640 goes into 3200 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 109520.2515625
Subtracting 3200 from 3200 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 16:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 109520.2515625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 109520.2515625 and a remainder of 0.0.
