45580394 ÷ 672 
We're looking to find how many times 672 goes into 45580394.

Advancing to step 1:
672 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 672

Advancing to step 2:
672 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 672

Let's proceed to step 3:
The number 672 fits into 455 0 times, leaving a remainder of 455.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 455, we get 455.
Take the next digit (8) from the dividend and append it to 455, then repeat: 4558 / 672

On to step 4:
4558 divided by 672 is 6 with a remainder of 526.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 4032 away from 4558, we end up with 526.
Take the next digit (0) from the dividend and append it to 526, then repeat: 5260 / 672

On to step 5:
When dividing 5260 by 672, we get 7 with a remainder of 556.
Write down 7 as next digit of the result. 
Result so far: 67.0
Subtracting 4704 from 5260 leaves us with 556.
Take the next digit (3) from the dividend and append it to 556, then repeat: 5563 / 672

Going ahead to step 6:
672 goes into 5563 8 times with a remainder of 187.
Use 8 as the next digit of our solution. 
Result so far: 678.0
If we subtract 5376 from 5563, we get 187.
Grab the next digit (9) from the dividend, add it to 187, then carry on: 1879 / 672

Let's proceed to step 7:
If we divide 1879 by 672, we get 2 and a remainder of 535.
The number 2 becomes the next digit in our result. 
Result so far: 6782.0
Deduct 1344 from 1879 and we're left with 535.
Take the next digit (4) from the dividend and append it to 535, then repeat: 5354 / 672

Let's proceed to step 8:
If we divide 5354 by 672, we get 7 and a remainder of 650.
Put 7 as the next digit of the answer. 
Result so far: 67827.0
If we subtract 4704 from 5354, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 9:
When dividing 6500 by 672, we get 9 with a remainder of 452.
Use 9 as the next digit of our solution. 
Result so far: 67827.9
If we subtract 6048 from 6500, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 10:
The number 672 fits into 4520 6 times, leaving a remainder of 488.
Put 6 as the next digit of the answer. 
Result so far: 67827.96
The remainder is 488 after subtracting 4032 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 11:
4880 divided by 672 is 7 with a remainder of 176.
Put 7 as the next digit of the answer. 
Result so far: 67827.967
Deduct 4704 from 4880 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 12:
1760 divided by 672 is 2 with a remainder of 416.
The number 2 becomes the next digit in our result. 
Result so far: 67827.9672
If we subtract 1344 from 1760, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 13:
672 can be fit into 4160 6 times, resulting in a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 67827.96726
If we subtract 4032 from 4160, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 14:
If we divide 1280 by 672, we get 1 and a remainder of 608.
The next digit of our result is 1. 
Result so far: 67827.967261
Subtract 672 from 1280 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 15:
The number 672 fits into 6080 9 times, leaving a remainder of 32.
The next digit of our result is 9. 
Result so far: 67827.9672619
Subtracting 6048 from 6080 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 16:
When dividing 320 by 672, we get 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 67827.9672619
Subtracting 0 from 320 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.

Our division results in 67827.9672619 with a remaining 3.2e-07.
