We're dividing 45170083 by 964 
Let's see how many times 964 fits into 45170083.

On to step 1:
If we divide 4 by 964, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 964

Going ahead to step 2:
964 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 964

Let's proceed to step 3:
964 goes into 451 0 times with a remainder of 451.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 451, we end up with 451.
Fetch the next digit (7) from the dividend, attach it to 451 and continue: 4517 / 964

Advancing to step 4:
4517 divided by 964 is 4 with a remainder of 661.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 661 after subtracting 3856 from 4517.
Append the next digit (0) from the dividend to 661 and continue with: 6610 / 964

Going ahead to step 5:
6610 divided by 964 is 6 with a remainder of 826.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Deduct 5784 from 6610 and we're left with 826.
Fetch the next digit (0) from the dividend, attach it to 826 and continue: 8260 / 964

Advancing to step 6:
The number 964 fits into 8260 8 times, leaving a remainder of 548.
Use 8 as the next digit of our solution. 
Result so far: 468.0
Deduct 7712 from 8260 and we're left with 548.
Append the next digit (8) from the dividend to 548 and continue with: 5488 / 964

Step 7:
964 can be fit into 5488 5 times, resulting in a remainder of 668.
Write down 5 as next digit of the result. 
Result so far: 4685.0
Subtract 4820 from 5488 to get 668.
Append the next digit (3) from the dividend to 668 and continue with: 6683 / 964

Advancing to step 8:
964 can be fit into 6683 6 times, resulting in a remainder of 899.
The number 6 becomes the next digit in our result. 
Result so far: 46856.0
If we subtract 5784 from 6683, we get 899.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8990, and continue the process.

Step 9:
The number 964 fits into 8990 9 times, leaving a remainder of 314.
Record the quotient 9 as the next digit in the result. 
Result so far: 46856.9
Deduct 8676 from 8990 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 10:
964 goes into 3140 3 times with a remainder of 248.
The number 3 becomes the next digit in our result. 
Result so far: 46856.93
Subtracting 2892 from 3140 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 11:
964 goes into 2480 2 times with a remainder of 552.
Use 2 as the next digit of our solution. 
Result so far: 46856.932
If we take 1928 away from 2480, we end up with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 12:
When dividing 5520 by 964, we get 5 with a remainder of 700.
Write down 5 as next digit of the result. 
Result so far: 46856.9325
Subtract 4820 from 5520 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 13:
964 can be fit into 7000 7 times, resulting in a remainder of 252.
The next digit of our result is 7. 
Result so far: 46856.93257
If we take 6748 away from 7000, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 14:
964 can be fit into 2520 2 times, resulting in a remainder of 592.
Write down 2 as next digit of the result. 
Result so far: 46856.932572
Subtracting 1928 from 2520 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 15:
The number 964 fits into 5920 6 times, leaving a remainder of 136.
Use 6 as the next digit of our solution. 
Result so far: 46856.9325726
Subtracting 5784 from 5920 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 16:
If we divide 1360 by 964, we get 1 and a remainder of 396.
Put 1 as the next digit of the answer. 
Result so far: 46856.93257261
Deduct 964 from 1360 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

After the division, we end up with 46856.93257261 and a remainder of 3.96e-07.
