67003943 ÷ 964 
We want to figure out the number of times 67003943 can be divided by 964.

On to step 1:
6 divided by 964 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
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 / 964

Moving on to step 2:
67 divided by 964 is 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Fetch the next digit (0) from the dividend, attach it to 67 and continue: 670 / 964

Step 3:
If we divide 670 by 964, we get 0 and a remainder of 670.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 670 to get 670.
Fetch the next digit (0) from the dividend, attach it to 670 and continue: 6700 / 964

Let's proceed to step 4:
964 can be fit into 6700 6 times, resulting in a remainder of 916.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 5784 from 6700 leaves us with 916.
Fetch the next digit (3) from the dividend, attach it to 916 and continue: 9163 / 964

On to step 5:
964 can be fit into 9163 9 times, resulting in a remainder of 487.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Deduct 8676 from 9163 and we're left with 487.
Grab the next digit (9) from the dividend, add it to 487, then carry on: 4879 / 964

Advancing to step 6:
If we divide 4879 by 964, we get 5 and a remainder of 59.
Write down 5 as next digit of the result. 
Result so far: 695.0
If we take 4820 away from 4879, we end up with 59.
Append the next digit (4) from the dividend to 59 and continue with: 594 / 964

On to step 7:
964 can be fit into 594 0 times, resulting in a remainder of 594.
The number 0 becomes the next digit in our result. 
Result so far: 6950.0
If we subtract 0 from 594, we get 594.
Append the next digit (3) from the dividend to 594 and continue with: 5943 / 964

Advancing to step 8:
5943 divided by 964 is 6 with a remainder of 159.
The number 6 becomes the next digit in our result. 
Result so far: 69506.0
If we subtract 5784 from 5943, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 9:
1590 divided by 964 is 1 with a remainder of 626.
Record the quotient 1 as the next digit in the result. 
Result so far: 69506.1
Subtract 964 from 1590 to get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Advancing to step 10:
964 can be fit into 6260 6 times, resulting in a remainder of 476.
Record the quotient 6 as the next digit in the result. 
Result so far: 69506.16
If we take 5784 away from 6260, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 11:
964 goes into 4760 4 times with a remainder of 904.
The next digit of our result is 4. 
Result so far: 69506.164
If we take 3856 away from 4760, we end up with 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

On to step 12:
When dividing 9040 by 964, we get 9 with a remainder of 364.
Use 9 as the next digit of our solution. 
Result so far: 69506.1649
The remainder is 364 after subtracting 8676 from 9040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 13:
3640 divided by 964 is 3 with a remainder of 748.
The next digit of our result is 3. 
Result so far: 69506.16493
If we take 2892 away from 3640, we end up with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

On to step 14:
964 goes into 7480 7 times with a remainder of 732.
Write down 7 as next digit of the result. 
Result so far: 69506.164937
If we take 6748 away from 7480, we end up with 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Advancing to step 15:
The number 964 fits into 7320 7 times, leaving a remainder of 572.
Put 7 as the next digit of the answer. 
Result so far: 69506.1649377
Deduct 6748 from 7320 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

The final outcome is 69506.1649377, with a leftover of 5.72e-06.
