We look at the division of 70643980 by 917 
We want to figure out the number of times 70643980 can be divided by 917.

On to step 1:
When dividing 7 by 917, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 917

Let's proceed to step 2:
If we divide 70 by 917, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Bring next digit (6) of the dividend behind the 70 and repeat the process: 706 / 917

On to step 3:
917 goes into 706 0 times with a remainder of 706.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 706 and we're left with 706.
Bring next digit (4) of the dividend behind the 706 and repeat the process: 7064 / 917

Advancing to step 4:
917 can be fit into 7064 7 times, resulting in a remainder of 645.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 6419 from 7064 and we're left with 645.
Take the next digit (3) from the dividend and append it to 645, then repeat: 6453 / 917

Going ahead to step 5:
When dividing 6453 by 917, we get 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtracting 6419 from 6453 leaves us with 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 917

Going ahead to step 6:
917 can be fit into 349 0 times, resulting in a remainder of 349.
Record the quotient 0 as the next digit in the result. 
Result so far: 770.0
If we take 0 away from 349, we end up with 349.
Take the next digit (8) from the dividend and append it to 349, then repeat: 3498 / 917

Moving on to step 7:
The number 917 fits into 3498 3 times, leaving a remainder of 747.
The number 3 becomes the next digit in our result. 
Result so far: 7703.0
If we take 2751 away from 3498, we end up with 747.
Grab the next digit (0) from the dividend, add it to 747, then carry on: 7470 / 917

Let's proceed to step 8:
7470 divided by 917 is 8 with a remainder of 134.
Write down 8 as next digit of the result. 
Result so far: 77038.0
Subtract 7336 from 7470 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 9:
1340 divided by 917 is 1 with a remainder of 423.
Put 1 as the next digit of the answer. 
Result so far: 77038.1
Subtracting 917 from 1340 leaves us with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Moving on to step 10:
When dividing 4230 by 917, we get 4 with a remainder of 562.
Put 4 as the next digit of the answer. 
Result so far: 77038.14
Deduct 3668 from 4230 and we're left with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Let's proceed to step 11:
917 can be fit into 5620 6 times, resulting in a remainder of 118.
Write down 6 as next digit of the result. 
Result so far: 77038.146
If we subtract 5502 from 5620, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 12:
917 can be fit into 1180 1 times, resulting in a remainder of 263.
The next digit of our result is 1. 
Result so far: 77038.1461
Subtracting 917 from 1180 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Going ahead to step 13:
917 goes into 2630 2 times with a remainder of 796.
The number 2 becomes the next digit in our result. 
Result so far: 77038.14612
Deduct 1834 from 2630 and we're left with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

On to step 14:
If we divide 7960 by 917, we get 8 and a remainder of 624.
Record the quotient 8 as the next digit in the result. 
Result so far: 77038.146128
If we take 7336 away from 7960, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Advancing to step 15:
6240 divided by 917 is 6 with a remainder of 738.
The next digit of our result is 6. 
Result so far: 77038.1461286
If we subtract 5502 from 6240, we get 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Let's proceed to step 16:
917 can be fit into 7380 8 times, resulting in a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 77038.14612868
If we take 7336 away from 7380, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 77038.14612868 with a remainder of 4.4e-08.
