45748373 ÷ 403 
We want to divide 45748373 by 403.

Moving on to step 1:
4 divided by 403 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 403

Step 2:
When dividing 45 by 403, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 403

Let's proceed to step 3:
When dividing 457 by 403, we get 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 403 from 457 and we're left with 54.
Take the next digit (4) from the dividend and append it to 54, then repeat: 544 / 403

Advancing to step 4:
If we divide 544 by 403, we get 1 and a remainder of 141.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 403 away from 544, we end up with 141.
Bring next digit (8) of the dividend behind the 141 and repeat the process: 1418 / 403

Step 5:
When dividing 1418 by 403, we get 3 with a remainder of 209.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Deduct 1209 from 1418 and we're left with 209.
Grab the next digit (3) from the dividend, add it to 209, then carry on: 2093 / 403

Let's proceed to step 6:
2093 divided by 403 is 5 with a remainder of 78.
Write down 5 as next digit of the result. 
Result so far: 1135.0
Subtracting 2015 from 2093 leaves us with 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 403

Advancing to step 7:
787 divided by 403 is 1 with a remainder of 384.
Use 1 as the next digit of our solution. 
Result so far: 11351.0
Subtract 403 from 787 to get 384.
Include the next digit (3) from the dividend after 384, then repeat: 3843 / 403

Going ahead to step 8:
403 can be fit into 3843 9 times, resulting in a remainder of 216.
Write down 9 as next digit of the result. 
Result so far: 113519.0
Deduct 3627 from 3843 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 9:
2160 divided by 403 is 5 with a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 113519.5
Subtract 2015 from 2160 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 10:
The number 403 fits into 1450 3 times, leaving a remainder of 241.
The number 3 becomes the next digit in our result. 
Result so far: 113519.53
The remainder is 241 after subtracting 1209 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 11:
403 goes into 2410 5 times with a remainder of 395.
The next digit of our result is 5. 
Result so far: 113519.535
Deduct 2015 from 2410 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 12:
If we divide 3950 by 403, we get 9 and a remainder of 323.
Write down 9 as next digit of the result. 
Result so far: 113519.5359
Subtracting 3627 from 3950 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Going ahead to step 13:
If we divide 3230 by 403, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 113519.53598
Subtracting 3224 from 3230 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
403 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 113519.53598
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
600 divided by 403 is 1 with a remainder of 197.
Record the quotient 1 as the next digit in the result. 
Result so far: 113519.5359801
Deduct 403 from 600 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 16:
When dividing 1970 by 403, we get 4 with a remainder of 358.
Write down 4 as next digit of the result. 
Result so far: 113519.53598014
Subtract 1612 from 1970 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

The final outcome is 113519.53598014, with a leftover of 3.58e-07.
